Worst purchase ever. I'd spend a bit more for the ATI 5850. However for $190, gogogo!I think i will go for a HD5830. From what i read on some reviews the difference between HD5830 and HD5850 is not that big.
the problem is that the 5830 is like 5% faster then a 5770...so if OP wanted 2X 5770 he will be sad with a single 5830...so just get a 5850 and don't waste more time.
With new drivers, I think the performance of the GPUs increased a bit. I think it's a worthwhile purchase for $190. Heck I'm tempted too.
Or you could grab a Sapphire 5770 since they're only $158 on Newegg.ca right now...
