I've been unsuccessfully looking around for some comparisons between the eVGA GeForce 7800GTX 512 and the new eVGA 7950GX2 1GB dual processor card. Does anyone know of any reviews or have any comparision experience? I noticed that the new 7900GX2s are less expensive than the 7800GTX 512s and that brought up a big question mark for me. Any remarks would be appreciated. Thanks.
