I personally like that Gainsward a little better than the Inno3d. I have no experience whatsoever with either brand, but the Gainsward card looks to be just a little higher quality, judging from the pictures I've seen of both. I really have no idea how cool each one would run, though; I'd guess they're both about the same. If you were really worried about thermal performance, I'm sure there are a couple aftermarket VGA heatsinks available where you live...
