Will it bottleneck?

[evanzfx]

Hello people of Steam,

I am genuinely worried that I'm going to bottleneck my graphics card so it won't perform to it's fullest potential. I am planning to replace my old GTX 550 Ti 1 GB card with a GTX 760 4 GB (most likely to get that) or a R9 280X 3 GB. I do not have enough money to upgrade my processor right now, so I'm worried that my cpu is going to be behind the gpu. I am planning to get a i7-3770K.

Here are my current specs, btw my PC was prebuilt;

Intel Quad Core i5-2300 @ 2.80GHz, 3.1 Turbo
Generic RAM 6.00GB Dual-Channel DDR3 @ 665MHz
Acer Predator G3610 Motherboard
EVGA GTX 550 Ti 1GB GDDR5 Superclocked
Windows 64 bit blah blah
Some 1 TB HDD @ 7200 rpm

I have ordered a new motherboard, psu, RAM, and case for Christmas (Don't worry, I made sure it will work together)

So, I'm planning to replace my 550 ti with a GTX 760 or R9 280X but I'm worried it will bottleneck my old i5-2300. What do you think? Would it bottleneck? Thanks.

You would gain about 8 fps extra with the i7-4770K.
