Thanks all,

just to clarify as my understanding of PC components has dwindled over the years, the more Ram I can get in a GPU lightens the load on the CPU? or am i way off the ball there? I would have tried to go for a bigger GPU and upgraded the ram on current PC, to see how that performs, but don't want to waste money on buying extra DDR3 ram, if I do have to go for a DDR4 motherboard!

I need to pull my PC out and check the component as i beleive i have either a 600w or posibbly 750w PSU as replaced it a couple of years ago.

thanks again for input.
