how much bottleneck?

[kjbrown972]

hi there,
so its my birthday in a few days, and i was hoping to upgrade my enitre pc. my dad just told me i can only upgrade the gpu though. my plan was to get a 670 and fx-8320.
here are my current specs:
cpu: amd athlon 2 x4 640
gpu: nvidia gts 8800 320mb
CM elite 430 case
ocz coreXstream 500w psu
1tb hdd
corsair vengeance 4gb ram
asrock motherboard
the only change happening now is the 8800 being changed out for a 670
now i know there will be bottleneck, but i want to know how severe it will be. i could go for like a 660 and save money, but if i upgrade in the future it won't be as good as i want. i have heard that i can still mostly get around 60fps on 1080p on things like bf3? that is all i care about.
thanks

I've run a GTX 480 along-side an Athlon II x4 640 without any noticeable slow-down, so if I were to guess, I'd say you'll be ok. I would wait to see if someone else has tried it though, as it's not a perfect comparison.

well i read somewhere that someone did this and still got over 60 most of the time, so thats good enough to me, i guess i will find out in a week

go for HD 7850 instead, it will be much balanced and you won't see any bottlenecks except a little in Skyrim and BF3 multiplayer, other than that it would be very good

i want to go for a 670 on the basis that when i do upgrade the cpu i will be getting a much higher frame rate, where instead by getting say a 7850 there won't be as much boost

ok ... just stay away from skyrim until you upgrade
