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?
The rule of thumb for that chart is you want to move up 2 levels to see a big improvement. Though 1 level can be okay too (close inspection).
you mean that is your rule thumb and a minority one since the chart's author states otherwise
"You can use this hierarchy to compare the pricing between two cards, to see which one is a better deal, and also to determine if an upgrade is worthwhile. I don’t recommend upgrading your graphics card unless the replacement card is at least three tiers higher. Otherwise, the upgrade is somewhat parallel and you may not notice a worthwhile difference in performance."
