Zotac GeForce GTX 260 "55nm Maxcore" 896MB GDDR3 TV-Out/Dual DVI (PCI-Express) - Retail (288-OK101-000ZT)
Cheaper, supports Physx, and this GTX 260 is based on 55nm
You can get eVGA model for a little more
EVGA GeForce GTX 260 "Core 216 55nm" 896MB GDDR3 TV-Out/Dual DVI (PCI-Express) - Retail (896-P3-1255-AR)
Would someone mind explaining what Physx is, and 55nm? I'm a real noob here...
Thanks for all comments so far.
