In a few months I'm going to build a HTPC with a low profile case. I do like to game and know that the selection of low profile cards isn't great, and the best ones are well below the performance of even last generations cards. I Googled this and saw that some LP cards will support SLI or Crossfire, but would this actually provide much of a boost over a single card? I don't expect to be able to play the latest games with everything maxed out. But if I could CrossfireX some LP cards and get maybe a 50% boost I'd probably consider it. I'm not a fanboy so I don't have a preference between ATI or Nvidia. Just want the best gaming I could get with a low profile setup.
