I'm planning to build a new rig within a couple of months or so. However I'm undecided as to whether to put 2 video cards or one. For once, budget isn't really a problem here (I'm gonna receive a tax refund of $3000 ) but I don't want to 'waste' it on stuff I could do without. What are the advantages of having 2 video cards (apart from higher 3dmark scores)? Unless I'm mistaken, vram doesn't add up so if I get 2 cards with 1GB vram each I'd still have 1GB vram. Will it make a difference in games like Oblivion and Crysis whether you have one 8800GTX or one 2900XT or whether you have two? (Keeping in mind that complimenting them there'd be a core2quad which I'd hope to OC to at least 3Ghz like my present rig, and 4GB of RAM).
