Best Nvidia Card Under £120?

[Ravious]

I currently have a HD5850 in my system. The reason I am looking for a nvidia card is because the program's I use (Especially Flight Sim and Folding) prefer nvidia cards for more than double the performance. I was wondering whats the best Nvidia card for under £120?

well not alot to work with but a 460gtx a 550ti or a 560 (non ti) fit that range I think any of them would show a boost over the 5850
