Hi i'm looking to upgrade my old reliable 8800GT 512MB. Ii'm looking for a fairly good performance increase for around the 200.00 mark and although i used to be a die hard nvidia fan it seems ATI is beating them in performance this time around so i'd go eithier way. Any suggestions?
Umm around the $200 mark, nvidia is in fact beating ATI with the introduction of the GTX 460. I would recommend the 1GB model (it's about $220 or so), which is somewhere in between ATI's Radeon 5830 and 5850 ($220 and $300, respectively). If you can't afford the 460 1GB, you can look into the 768MB model ($200), but it doesn't perform quite as well (I'd still take it over a 5770).
Both versions of the GTX 460 are a good deal. I would lean more towards the 1gb model if you plan on SLI in the future. 192bit/768mb is acceptable for a single card but the memory systems are redundant in SLI and it wont be enough to fully utilize the processing power when you have 2 GPUs working together.
the 1 gb version will be a better choice since the extra buffer size will help when you enable anti alysing and other eye candys that takes up alot of mem it will also let you run higher resolutions more smoother since it has that extra mem.
