Correct me if I'm wrong but all p55 mobos downscale the memory bandwith from 16x to 8x when xfire/sli is activated. I would only install 2 cards if I had a x58 mobo and not just any mobo for that matter.

+1 for the Cooler Master Hyper 212 Plus, its an excellent cooler for the $30 price tag Add another fan for $10 and you've got a push/pull system

The 5850 is comparable to the GTX460 1GB than the 768MB version as the 768 beats out the 5830 only by the slimmest of margins, IMO.

The brands I would choose for my cards are XFX for ATI and EVGA for NVidia as they both have the best warranty and customer service.

Everything else looks great, good luck with your build sdub

You're correct, although in most cases you won't notice any performance difference from the decrease in bandwidth. Still, I always prefer a single-card setup rather than multiple cards.

chipset limitations play a good role if youre shooting for bench world records...else..


4x to 16x takes a 10pct hit. 8x to 16x half that.

Just a follow up on my thoughts on the SLI/Crossfire issue. Zero is right and dang made a point about specific benchmarking tasks. Yes games today are not affected much by reducing memory bandwidth in SLI/Crossfire, but surely games that push the memory bandwidth will be coming out soon. These 32 memory lane mobos have been out for a while and using them for SLI/crossfire this summer and beyond should yield overall NOTICABLE improvements in efficiency, not in power. The power is already there but it just can't be utilized in most of the mobos that advertise SLI/crossfire-ready on their packages.
