Hi i need help with my tf2 lagging

[LongDongSilver]

Ok so i play tf2 on my laptop(Toshiba satelliteC855D-S5201-With 4 gb ram-AMD E1-1200 APU Processor-Radeon HD Graphics-1.40 Ghz) It is very laggy when there is alot a gunfire on the screen.I've tried several fps configs and it barely helped by like 4 frames.How can i fix this issue?,Is my computer just not strong enough to handle tf2 or is there something Wrong,I just want a way to play my game smoothly and be able to enjoy i.P.S i usually get from 20-30 frames with nothing really happening with several people and gunfire i get from 10-3 fps

AMD E1-1200 is coupled with a Radeon HD 7310 GPU.
Neither of which can handle most games very well, as it was made just to provide basic hardware acceleration for media/entertainment purposes, nothing close to gaming performance. Get a better laptop, or build a custom desktop. Nothing u can really do on that current system to make games run better.

Well i'm thinking of building a custom computer but i have one issue how much should the budget for it be

[_I_]

in short, cpu too slow and gpu too weak

amd duals almost always are too slow for tf2
it only needs 2 cores, but amd 3ghz is not fast enough
and a good gpu, amd x310 is a bottom of the barrel gpu
7 = gen
3 = strength (max is 9)
1 = low subgrade (max is 9)
0 = makes the number look bigger

for around $550

the reason why everything is laggy is that E1 cpu is the bottom of the barrel when it comes to cpus, view it like a Intel atom.

If your on a budget, the build _|_ is suggesting is great one. Though, if your only gaming with this rig I would change the cpu to a intel G3220 and get something like a gtx 750 or amd equivalent.
