Hey guys, I was just wondering whether an AMD 7750 BE @ 3.0Ghz~ with 2gb single channel DDR2 800 CL5 would bottleneck an HD4870? I'm thinking yes, but the one thing I'm not sure on is how much it would bottleneck, would it be worth buying a Phenom, or an i5?

Thanks heaps

Depends on the game... some games are very cpu limited and some are more video card limited. 

What size monitor and what resolution are you using?  What games do you play?

17" @ 1280 * 1024 at the moment, but soon a Viewsonic 24" @ 1920 * 1080, when I get the HD4870. I play semi-dated games like Titan Quest, most games on the Source engine, Killing Floor, Call of Duty series, I've played most mainstream games and I'm intending to continue this pattern. Also, do you think getting a HD5770 might be a better alternative because of DirectX11? I have little intention of getting any more monitors, so I'll just run a single one

Thanks for your reply

Sure the Athlon 7750 is older tech now but I don't think a 4870 1GB will be significantly hampered by a 3ghz dual core.

The 5770 is the same or slightly slower than the 4870 in most games and costs $40-50 more currently.  I don't think it's really worth it many DX11 features are software and API changes and do not actually require DX11 hardware.

In a year or two when DX11 hardware tessellation and shader model 5.0 is mainstream you'll probably be ready to upgrade the cpu/mobo/memory/graphics again together anyway.
