This may have been answered before, but I would like to know if allocating extra memory to onboard graphics would improve preformance. I am aware that a graphics card is the obvious solution now and in a month I'm likely going to buy 2xHD6950's, Right now however, I don't have the money. If it helps I'm running a Phenom II x4 black edition non oc'd running@ 3.4 ghz, the onboard is a radeon hd 4250. Im running 16 gigs(4gbx4) of G Skill sniper ddr3 @pc1333. I would like to know if this is possible, and if so, if it is effective. Thanks!

...more importantly, even if you could allocate more memory to the graphics subsystem, it would make next to no difference. The on-board graphics chip's performance isn't limited by lack of memory. At 1920x1080 or lower resolution, 1GB of memory is barely even used totally. It's limited by its lack of power. Few streaming processors, low memory and GPU clock speeds, low no. of ROPs, etc.
