Graphics cards help.

Okay, I need an expert please. I currently use a Dell XPS 630i desktop for basically everything I do, programming, gaming, etc... I've got 2 9800gt 512Mb running in it right now, but I'm thinking about buying a 295 for it and I have some questions: First off, is it worth it to upgrade? Would it be able to outperform my current setup? And second, if not, would I be able to stick a gtx 480 in it then, and would that be worth it?

I dont know about completely outperforming your current desktop, but it really depends what particular type of 295 youre going to purchase. Is it a 295 with 1gb memory? More information would help, I can tell you everything you need to know if you just provide a tad more info. If you purchased a gtx 480, im 90% sure it would outperform your current setup and the 295 by far.

Thanks,
