Hi folks, I want to get back into PC gaming at the least expense possible. I have an ageing PC which has the following components: MSI K8N SLI mobo (s939) Athlon X2 4200+ 2 GB Ram XFX Nvidia 7900GT 256mb Would a new graphics card let me play some modern games, or would my graphics card run anything current if I changed the mobo, processor and Ram? Would picking up another 7900GT cheap for SLI be of any use? Basically, is anything usable, or should I just start again?! Many thanks for any advice!
