I'm looking for a gaming graphics card for not a lot of money. I don't need to be able to play really high end games, I play mostly Source engine games like Half-Life 2, Counter-Strike: Source, Team Fortress 2 and so on, and I'd like to be able to play games such as Fallout 3 and Oblivion. I'm kind of a beginner so please bear with me. The CPU was assembled by someone else.
Here's the info straight from the "dxdiag":
Processor: AMD Phenom 9850 Quad-Core ~2.5GHz
Memory: 3328MB RAM
Operating System: Windows XP Professional(5.1, Build 2600)
Current Display Mode: 1024 x 768 (32bit)(75Hz)
The first two cards I linked would be good choices for what you want to do and the 7750 while a good card is as you can see over your budget. the final two are less expensive and will play some games well and it is most likely they will play the games that you want. The choices are slim when it comes to a low budget and you have to balance what you want vs what you want to pay. Your resolution is on the low side and the games are on the average side so with medium settings these cards will play your games.
