I want to buy a new VGA card for my desktop so I can play this year games comfortably, I don't want to pay more than
180$. My motherboard is the Intel DP35DP, CPU: Q6600, RAM: 4GB DDR2 800MHz, Windows 7 64-bit is installed and I currently have a 7300GT 512MB VGA.
The blurbs in that article about resolution use adjectives that greatly overstate things imo. The GTS 250 will be good for your resolution but not great. I would recommend the HD5770 or at least an HD5750 so you have a DX11 card. If you don't want either of those the HD4850 is usually cheaper than the GTS 250 while offering similar performance.
