1950 PRO should outperform the 7950 GT according to the numbers. However, assume they're similar for a minute (or even for argument's sake that the GT is a bit faster)..........real world gaming difference will mean a couple of fps. Seriously. So, all things then being equal, the PRO is a much better deal due to the cheaper price
And I generally like NV, and I'm recommending ATI. LOL. But not just me, most people in that thread say the PRO as well.
Me, I go for bang-for-buck. At that price, the PRO seems like a much better deal, especially if it is faster than the GT.
In the end though, I'm sure both will perform well. So I would think it comes down to price........?
