I have a very low end setup that I want to upgrade. Dell OptiPlex 760 (Small Form Factor) Processor: Pentium(R) Dual-Core CPU E5300 @ 2.60GHz Memory: 4GB DDR2 RAM Graphics: Intel(R) Q45/Q43 Express Chipset (Microsoft Corporation - WDDM 1.1) OS: Windows 8 x64 I only want to play GTA San Andreas and a bit of CSS. So I am looking for a cheap PCI Express graphics card but it must be a low profile card due to the SFF case. I don't mind second-hand. Which card is the next step-up from my integrated graphics?
