ok i had a hd 4850 1g, for christmas my mom got me a new card evga gts 450 01g-p3-1450-tr at a local computer store for $170. i looked around a little online about the gts 450 and people were saying to just get the gtx 460 for $20-$30 more, because its better for not much more money. i found a evga gtx 460 768-p3-1360-tr on newegg for $140 after rebate. the gts 450 was just released 2-3 weeks ago and the gtx 460 was 4 1/2 months ago. sooooo should i return the gts 450 and get the older gtx 460?
