I have been looking for a new upgrade from my Radeon 4870 and was thinking I would go to Radeon HD 7870, but I found some benchmarks with a large sample size that seems to show that the Radeon HD 7870 is outperformed by the GTX 480 (3451 vs 3558). I looked up the specs on the GTX 480 and the HD 7870 and got
Actually the HD 7870 is a few percent faster than the GTX 480, overclocks better consumes less power and works more silently.But you pay for that big time!If you want the most power you can get for that price i say go for a Dual GPU configuration like maybe two of those here.Each of them is as fast as a GTX 480 but is also newer and consumes less power.
I really like that version of the 560Ti myself. And while it is generally all around better from a power etc point of view don't dismiss the 480 out of hand. Look at gaming performance reviews of the kind of games you play and see which one performs better at those titles.
Also remember as with all these reviews, unless you realise and take into account that the 560Ti from Zotac linked is about as fast a clocked version you can get, and also that the 480 in the review will be a stock standard card, then things can get twisted quite quickly.
A review of a tweaked 480 would like wise list a standard 560Ti which it would make look silly compared to the Zotac version.
