i was just wondering if the athlon II x4 620 will be bottlenecked with 2x 5770 GPUs?

or will it be wise to upgrade it from athlon II x2 240?

i currently have:
athlon II x2 240
ATI 5770 gpu

i am planning to go on xfire and wondering if the athlon II x4 620 can handle it..

suggestions and comments are welcome..

tnx in advance..

Best solution

no, a 620 wont be bottlenecked by 2 5770. actually 2 5770 is = to a 5850. no a 5770x2 with a 620 would work very well together.

At 2.6 ghz it definitely WILL bottleneck in some games at some resolutions. Thats why if price is a factor, people go for the higher clocked tri-core. That 620 definitely needs to be o/c some.

I just recently noticed that some newer engines do some software level post-processing for your graphics, but I can't see how increasing your GPU power could even get close to bottle-necking in the CPU.

The only real thing that can bottle-neck any quad core CPU is an advanced physics engine. Screen setup is fairly cheap and telling the GPU to render a higher res or AA doesn't add any more work to the CPU
