you will only have 8 lanes of bandwidth for each video card, however that is still more than enough for those cards, and they will not be bottlenecked.

looks like a very nice system, it should do well.

Hello and welcome to the forums
P55 chipset supports CrossFire at dual 8x mode,where as X58 chipset supports it at dual 16x.However the performance difference isn't much, and dual 8x will perform as good as dual 16x in almost all games.So you'll be fine running 2 5770's on that board.

the motherboard you have chosen is exactly what i would recomend.

as you can see from my signature, i am running the same motherboard (though the AMD version). its an excellent choice. the UD4P is the best price/performance board on the market IMO.

4gb.

the 1156 socket motherboards operate in dual channel mode for RAM, so you get more performance when using an even number of sticks. 6gb sets are designed for use with 1366 socket mobos, which use triple channel RAM in multiples of threes.

yes, the ssytem will handle crysis well, its still going to be less than 60fps (the game is very demanding) but will be playable at max settings.

as for the ram upgrade, you want to go from 4gb to 8gb. going to 6 will mean the RAM will operate in single channel mode, so you will lose some performance.

It depends on your resolution, but 2 5770s can handle Crysis on resolutions like 1920x1200 fine, i think you'll get about 30-40 FPS on 1920x1200(maxed out)

you seem to know the basics.

the main things are, don't skimp on a PSU (get a good brand like corsair or seasonic), make sure you know hot to apply TIM (even if you are using stock heatsink, its worth reapplying some good thermal compound) and take the time to do a fairly decent job at wiring. a cool PC lives longer.

also, i see a lot of people using two crossfire bridges when using two GPUs. this is in fact not correct, and can actually cause some issues. for two cards, you only need one crossfire bridge.

you should be set though. if you run into any problems feel free to PM me or just revive this thread.
