Widescreen Gaming Forum

I've been looking around the forum for discussion on videocards and/or SLI for 5040x1050 resolution gaming but haven't found anything. I'm surprised, actually.

So far I'm running an i7 920, 6GB DDR3, and a GTX 260 Core216: how will that stack up for Source-based games, do you think? I've got plans to play pretty much anything that supports the resolution - I've got Bioshock and HalfLife 2: CM10 on deck - so I'm wondering if I should drop a few bucks on a better card (more VRAM) or perhaps in another GTX 260.

Does SLI really help since this is such a large res? Feel free to just post a link to another thread if I've failed in my searching. Thanks!
