Nice guide. I take it there is only the hardmod option available if I want to increase my HD4870X2's clock speeds? No raising the VGPU to 1,5V via software like back in the X1900 days?

Trying to judge if it's worth the hassle.. I got my card watercooled and cold all right (usually below 30C core, card loop only), and it can do a 3D06 pass at around 850 Core. DOesn't like memory clocking at all though, even 950 will give artefacts. What'd you recon I could reach with a VGPU mod, 930-950? I mean it already does 850... oh yeah, waht's the stock VGPU on those cards anyway? I haven't modded a GFX card since my 8800 GTS 640 lol.
