The 465 is a little longer than the 460, doubt it would matter in that case though. I recently ordered a 465, but only because it was 40 bucks cheaper than the cheapest 460. All the reviews I read had the 460 as the better card, unless you get lucky and get a 465 that unlocks to a 470.
465 is not a bad card, but the 460 is a really good card. I wouldn't get the 465 unless like me you find a really good deal on one, especially if you plan on SLIing them (unless you want 3 way sli, 460s won't do that)
Don't bother even thinking about the 465 (google it for reasons).. Get the 460 1GB.. They scale nicely when put in a 2-way SLI config matching (sometimes surpassing) the performance of a single GTX 480..
Yet, a lifetime warranty isn’t very valuable once technology improvements make an old card worthless. While cards more than three years old are often in line to be replaced, the few that remain in use add significant support cost to manufacturers who offer longer coverage periods. Asus, ECS, Gigabyte, and MSI try to balance their cost against the needs of most buyers by providing a warranty that’s exactly three years long. Among these manufacturers, Asus has the greatest peak cooling capability and clock speed, Gigabyte has the lowest price, and MSI falls in the middle with a huge cooler and moderate price.
Forget about the 465, it runs warmer and trails the 460 in most tests.
