Amd or intel
i know its a big question but looking at either the i7930 or recommended amd. AMD are cheaper and seem to able to clocked to higher speeds. Any recommendations would be a great help. Mainly gaming
Higher clock does not mean faster processor. Core CPUs do more per clock cycle. However, based on the price of $160 for Phenom II x4 955 or $290 for a core i7 920, the phenom is better value.
I do recommend the phenom II x4 955 because really, unless you plan to be crossfiring two radeon 5970s, you will not notice an increase in performance. That $130 would be much better spent on a better graphics card. If you were considering a radeon 5850, the money saved could bump you up to a radeon 5870, which by comparison would increase your gaming performance massively.
I recommend this specific model of phenom II 955 because of the better C3 stepping. Note the "CPU box number":
And here it is on newegg, if you buy from there:
Would you like further help with the rest of your components?
Quote:thanks guys was looking to crossfire 2x5770 but currently got a single 4870. not sure which way is best to go either keeping 4870 and adding another card or just buying to 2x new cards? also any mobo recommendations would be great.
The 4870 performs pretty much the exact same as the 5770. The 5770 has DX11 though. So it's up to you.
Personally, I would rather keep away from crossfire. A more powerful single card will provide more consistent performance. And I am unsure if they have completely solved the stuttering issues. Even with the latest drivers, I had stuttering issues on the dual chip Nvidia GTX295 I tested out in the past month. Not to mention that the increased cost of a good crossfire board will pretty much nullify the better cost of two 5770s.
$340 for two 5770s:
$400 for one 5870:
Anyway, here's a good motherboard that will suit your needs either way:
Dual link is 8x for the pci-e slots (for crossfire).
