I'm just wondering, is the performance difference between these that big to warrant such a price difference? I'm considering getting the XFX GeForce 6800GT PCI-E from Monarch for $368, but the BFG GeForce 6800Ultra OC PCI-E for $540 looks so tempting. What do you guys think? Is it worth it or is the XFX 6800GT a good choice? Keep in mind that I'm planning on only using one card for now; I was thinking of buying the second to run in SLI in about a year when prices drop and such. Please give me some advice--I need it badly.
