So I'm looking for an under $300 upgrade that would work with my existing motherboard:
MSI X58 PRO-E SLI / CROSSFIRE MOTHERBOARD

I'm currently using:

ATI RADEON 5770 1GB DDR

I was planning to put the second graphics card in the second slot but from poking around and reading some of these threads perhaps that isn't the best idea?


The processor is :

OEM INTEL i7-930 2.80GHZ 8M LGA 1366

if it makes a difference.

I'm using two hdmi capable monitors so I'd love two hdmi ports.
