definately the 650ti.im currently using 1.i play most of my gamz on ultra.
u can get the 650ti for around $130 but if u add $20 u get e boost version (2gb) which is awsome
Where can I get one of these $150 650Ti Boost 2GB cards?!?
In all seriousness - the superior GTX 650Ti is at a great price right now - available at $120 on Newegg.
