Hi, my girlfriend is looking for a pc to play games on (her laptop is struggling) and we're on a bit of a budget. I have an old media PC that is no longer needed, I was hoping someone might be able to give some advice on if it might be worth installing a graphics card and which card might be appropriate. The machine is currently comprised of: Intel® Pentium® Processor E2180 Asus P5K-VM 2 x 1024MB RAM Windows XP Professional DirectX 9.0c Ideally I'd get a GPU powerful enough to run Source games at a decent fps at high settings. But, I'm extremely unsure because I don't want to have a gpu go to waste when the mobo/cpu can't keep up. There are also some size limitations and power supply concerns thrown in to the equation, something small and efficient should fit the bill. I was wondering if someone could make some gpu suggestions that might be suitable for this machine? It's her birthday soon so any help would be hugely appreciated!
