True
Must admit I hadn't thought that the gfx card itself could make much of a difference. There's a few things I'm going to play around with on the PC to see if they help but if it's borderline then I might finally rebuild the thing to a higher spec - just wondered what the minimum was and whether I could get away without spending too much money.
I'd rather not buy a better gfx card only to find it's really the CPU and then have a GFX card that isn't much good for the replacement board thjat's needed for the CPU.
