I'm currently running an X2 4200+ at 2.51 ghz, and wondering if such a CPU would bottleneck a 4870? From what i've seen, most games don't even max out the CPU, while my X1800XT struggles greatly. I am thinking along the lines of getting the 4870 now, and a few months from now upgrading the rest of the system when i'm in the US.
Yes, It will bottleneck 4870
Mine is clocked at 3.2 Ghz and still bottlenecks my 4870, espatially on crysis warhead(this game is huge cpu demanded)
BUT, you'll notice GREAT performance boost anyway.
I've upgraded my 3870 to 4870 and noticed 50-60% performance boost, with better cpu it have to be more than 90% but I admit that cpu is bottlenecking my 4870. Can't wait for phenom 45mn release
nice benchmark kim, same speed with my cpu. that will be my performance when i get an HD4870.
to Chipshardy, the only reason to buy an HD 4870 is to play crysis.
with other games, 4850 is very good while 9800 GT / 8800 GT is good.
