Nice try on save but no catch. You just pushed him away from the simplest solution (tomshardware) into a potential pitfall (your link). Prime example on how not to do research, without even checking the facts before posting.
Although I
generally agree with what you are saying, you might practice what you preach.
I wouldn't want to pay 200 bucks for a radeon 4890 if I can get the same card relabeled, boosted with dx11 support and clocked higher for 180 bucks as 5770.
The 5770 is not a relabeled card. It is a brand new card with 40 nm tech that is exactly half the spec of the 5870.
The 5770 is also not on par with a 4890; it is barely on par with a 4870.
"It's tempting to compare the card (5770) to the HD4870 and HD4890, but the HD5770 has only half the memory bus width of the entire HD48xx series; however every single 5xxx card runs GDDR5 memory at very high clock rates. The memory bandwidth of the HD5750 compares favorably to the HD4850, at 73.6 GB/sec versus 63.5 GB/s, but falls way behind the HD4890 which runs at 124.8 GB/s, as well as all the NVIDIA G200-based cards. It's the penalty ATI paid for slicing the "Cypress" directly in half in order to get the "Juniper"."
5770 BenchMarkReviewAs for the original question I agree that RAM will provide the biggest benefit. I wouldn't want either of the suggested vid cards, even at 30 bucks, but if that is your budget limits, then ...
