Yes, confirmed.
I replaced my 1024MB of Pc5300 Ram with 2048MB of Pc 6400 Ram.
Without touching anything else inside I get much higher Fps in any App I try.
I can use higher settings on graphics and still get higher Fps.
As for graphics cards I have Nvidia 8800 GTS with 320MB memory. Got it as a replacement for a faulty card. It works really well but the extra memory you get on a 520 card is probably needed in some games.
Check that your new card fits in your cabinet, some of them are really long.
And that your Psu can deliver the needed power.
