What CPU goes good with a Radeon HD 7870 2GB?

[Macky]

I'm new to PC building, I've only been doing it for around a year. I got this awesome new card, but my CPU is lacking. I only have a AMD A8-3870k Llano 3,0 GHz. My budget is around $150-250, and I also need a new motherboard. Can anyone recommend me a good cpu?

Bonus points if you recommend me a good motherboard.

[Macky]

I got the same kind of gpu, before I will crossfire I need a new case. This card is really long and it hardly fits in a mid tower.

[Macky]

The reason I want a new CPU is because mine is bottlenecking in some games, and I want an Intel cpu. I guess I could just liquid cool my cpu now and OC it, but im kinda scared to take off my heatsink because I was messing with my CPU before I knew a lot of processors and accidently broke off couple of the pins. My psu wattage is 630, I will need a new power supply if I want to Crossfire it. You do make a good point, but I just want a vicious gaming rig so I dont have to upgrade for like 6 years.

[_I_]

the trick with removing a heatsink is to twist is by about 5º each way then lift it off, dont pull

your a8 board/cpu would make an awesome htpc setup

[Macky]

I did it before I knew about not using any force. I also heard that you should turn on your computer before you do it so it can melt the thermalpaste. I might just liquid cool my CPU and OC it to 3.3 Ghz. I tried overclocking to 3.3 one time and my perfomance in Far Cry 3 on Ultra was like averaging 50 frames before my computer bluescreened. If I do end up crossfiring my cards I will have to get a new board just so I can make it run the best it can.

I found some parts i'm considering buying.

It's going to cost around $455 without shipping and the extra graphics card.
$704 with the card

I don't mind raising the budget to around $350-400 to get a better motherboard, the Sabertooth z77 is really expensive but I might be able to fit it in.

You shouldn't need to.

An i5 3570K would be hard pressed to be bottlenecked by TWO GTX 680s in SLI in nearly all games.

Since you only have the 7870, there's no need to go crazy on CPU power unless you plan to upgrade in the future. An i5 3550P or 3470 would work just fine.

I'm probably going to keep the 7870 for a while since I bought it not too long ago, I might crossfire 2 7870s if I have the cash. I'm ptobably going to go with the i5-3470 and the ASRock Z75 Pro3. The last thing I would love to get is case that has better cable management, my Rosewill Challenge has horrible cable management.

On the cable management side there's a dirt cheap NZXT Gamma Classic case that I love that has pretty decent cable management for a paltry $40. No USB 3.0 front panel jack and a front headphone/mic port that has interference but it keeps things really cool and actually has cable management; at $40!

I also have the Corsair 300R and am overall satisfied, even though it really needs at least two more fans to make it great (a 140mm front fan and a side fan).

There's very little reason to spend through the nose for a case. As you start straddling the $80 mark you reach a point where the benefits provided by such a case are things you'll probably never utilize in the entire life of the case.

Things like 10 hard drive bays, 6 disc drive bays, and a myriad of crazy configurations.

They're great if you need things like that, but utterly wasteful if you don't.

My 300R has just enough drive bays for me, though it could probably have done with one more disc drive bay. I've stuffed a hot swap rack, a 3.5" adapter for a card reader, and a DVD-R drive as well as two 1TB HDDs and an SSD. It's not a perfect case and there are still things that bother me about it, but it fits my needs snugly.

It's not my graphics card, I stated before that it was my Processor. The GPU I have is a Radeon HD 7870 2GB. I can play BF3 and Farcry 3 fine, but my fps goes up and down way to often and I see playing on Ultra with the same card as me and getting 60 frames avg.

Also the reason why I want a bigger wattage for a power supply is so I have room to upgrade later in the future.

My mother currently is an ASUS F1A75-M. Just so you know, I didn't build this computer, I bought it prebuilt and just added a new CPU, case, powersupply, and graphics card.

I would love an intel cpu, but they are way more expensive than AMD. Im trying to decide if I should just OC my cpu now or get a new one, if I get a new one I can oc that one too.

this will fit in you motherboard..suppose to be a great cpu...

189 bucks

why spend money if you dont need to...that power supply you have may run everything in crossfire just fine...theres no way to mod your case to fit 2 amd cards in it...like remove some drive bays that arnt used...

[bloodraven43]

hell get a liquid cooler like the 2.0 water pro by thermaltake and overclock that bioche...that could be why your bottlenecking...thats your cheapest solution...freaking 100 bucks and game on

The FX-8350 is a very good AMD CPU, barely keeps up with the i7-2600K.

No that won't fit, my motherboard has a FM1 slot. I can't put another card in my case, I had to move my hard drive down one slot to get it and if I put another card in, I wont be able to plug anything in my hard drive.

bloodraven says
i know this but its a cheaper solution to his problem....i7 cpus like the ivy bridges like i own are the best...slamming mobos with 6gb sata,raid config,pci-e 3.0,usb 3.0 slots,etc are the best

asus maximus formula 5 z77 board
i7 3770k ivy 0c@4.6 mhz
2x500 raptors in raid 0
1x64mb sata 6gb ssd for intel smart responce
16 gb of gskill 1600 mhz z77 comp ram
evga gtx680 ftw 4gb card
in win dragon rider case
1200 watt gold grand thermaltake psu
bluray burner thats comp with any dvd/cd config
2.0 water pro liquid cooler on cpu
big water 760 liquid cooler for the special water cooling app on mobo for the vrm

thats my rig im well aware of whats primo or not primo...just trying to help this dude out and save aliitle cash.my rig might be overkill but guess what...i play anything i want in ultra maxed out setting...everything.

[bloodraven43]

@banzaigtv ...btw what are you playing games on??? just wondering since you so tech savy...lol...rathen then attack my posts ,check yourself and help this dude out with a cheap solution to his problem....the only thing hes complaining about is bottlenecking and or slow downs on certain games...his rig isnt that bad...i think with a correct water cooling on the cpu a better overclock of cpu can be achieved and stop his lagging...why spend money if you dont have to

Then if his CPU can overclock well, then all he has to do is get a liquid cooling system and perhaps a better power supply. He can then overclock the CPU to at least 4.5 GHz or so. Then his problem would be solved.
