Worth upgrade?

[testyvis]

I currently have 2 x GeForce 6600GT 256mb and im thinking of upgrading to a single GeForce 7900 GTX 512mb. The thing is its going to cost around £320. Am i going to see a worthwhile improvement in my gaming performance.

I know the new card will be better, but what im asking is will be good value for money upgrade or just a small amount better?

You'll see a very big improvement. But if you're pretty tight on money, then hold on to the 6600GTs, and then get a top-line next-gen card.
