Not really any skin of NVs nose. It's the same dam chip they're making really. Just the OEMs stopping putting one name on the stickers/box and put on another.
OcUK have just started to flog off there Point Of View ones for £80 for the 320mb and £100 for the 640mb.
I have the 320mb and its a great card if only i had an SLi board i would jump at getting another even if i do hate SLi!
EDIT
Just noticed this going for £53 which is very very tempting... but just to go SLi... urgh do i really want all that trouble again and would i really see the performance gains for the extra £150 it would cost?!
