A bit off topic, I know, but there are guys lurking here that can help me. Running on a shoe string, I have a fairly ancient PC. Limited to Pci 2. Twin Intel Xeon 3.4s 8 gig ram Win 7 Pro x64 It is running quite well with this 2 gig DDR3- https://www.asus.com/uk/Graphics_Cards/GT610SL2GD3L/ A view please on if you think this 4 gig upgrade would be worth a shot- https://www.asus.com/uk/Graphics_Cards/GT6304GD3/ I am concerned by mixed reviews and the fact that it does not require a Pci power supply- seems to imply it is a bit light weight. But at around £50- what do you think?
