Hi, I have an old system which I definitely need to upgrade.
Currently I have:

Gigabyte GA-M61PME-S2P
AMD Athlon 64 X2 7750 2.7GHz
2 GB RAM
ATI Radeon HD4350

Obviously I need to upgrade everything but I will find RAM easily. For now I only need help with GPU. So I'd like a GPU that can play all new games on medium settings at 1280x720 resolution. I found this one - http://www.powercolor.com/Global/products_features.asp?id=373 - for 50 euros so I was wondering if it's good enough. I also found a few of GT 620's and 630's for about the same price but I don't know if I should mix AMD processor with a Geforce card?
Any help will be appreciated!
