Hello all, this is my first question on this forum

I was just wondering what would be the best thing to upgrade on my pc to increase my game performance

Here are my specs:

Processor: AMD Athlon 64 X2 5600+ (2.8 ghz)
RAM: 2GB running at DDR2-666
Graphics Card: Sapphire HD3870

I just want to be able to run crysis at fairly high quality, with a fairly high framerate

Thanks for any response, Leander24.

upgrade either of the following you're choice

RAM
GPU
HDD

I know that with the Ram you have it starts to glitch on some games after a certain amount of units have been created. Well that is what it did on mine anyway. RAM is a big factor in gaming along with the GPU. I don't know what else is involved within gaming you would hve to ask other people.
