if money is not really an issue then upgrade now, but if yu arelike me and have to save every penny for an upgrade then wait till later this year. dx10 cards are coming soon and they will make all except top end cards obsolete. save your money till then and get a really nice one......OR......save a little more than the 7600 and get a 7900 (they can run every game out on high and don't cost too much), then when dx10 comes out and the prices drop, get a second for SLI. there, you have three good choices, each for a different budget. hope this helps.
So it Goes.
