I don't wanna spend too much, the only games I play on my PC are WOW and Minecraft but I often get frame rate drops and it's started to annoy me.
My current specs:
AMD Athlon 64 X2 Dual Core Processor 4000+ 2.1ghz
3GB RAM
GeForce GT 220
My budget is £100 but would prefer less if possible.
I don't expect to run them on max settings but I'd like to be able to at least run them on low-medium and have a steady framerate.
Someone recommended a "msi r6670", is that any good?
