Upgrade from 560Ti to 760/770 - Will i3-2120 bottleneck?

[Lastro1]

Currently have a 560Ti, i3-2120 at 3.3Ghz.

I wish to upgrade to a GTX-770, since I can get one for something like £230 here in the UK now. Will my cpu bottleneck this gpu noticeably?

-Also will the performance increase from the 560ti to a 760 be significant? I can't find any fps graphs for it, so any would be hugely useful.

Games I play: Dota 2 (mostly), BF3 (now BF4).

-Oh, my psu is only 500W, do I nee to upgrade this?

I would look at a i5 3470

Battlefield likes cores a lot, a gpu upgrade would be worthwhile but at this point the i5 would offer better multiplayer battlefield performance

i3 3220 won't bottleneck 760 but it will indeed bottleneck 770 a little bit

I spend about 90% of my time playing Dota 2. Does anyone know the premium build to play dota 2?

Also what PSU do I need? I currently have 500Watts.

hd 7770 can run dota 2 at 1080p everything on/high...dota 2 is a light game

There's something VERY wrong with my setup then!
