But this is the thing, he promoting the 4890 like its the greatest thing since slice bread. The thing is although the 4890 can beat a gtx 285 when overclocked, however, its obvious that a gtx 275 can do the same. However, the gtx275 always not even mentioned in his post and thus by default, the recommendation goes to the 4890. It should also be inherently obvious although he never mentions it, that a gtx 285 OC can likely beat a OC 4890.
And atleast in Canada, a highly overclocked 4890, cost as much as an overclocked gtx 285.
This is the closest thing I can find to a 1000mhz 4890(its a 950)

And its at its cheapest price. 330.
This is a OC gtx 285 its 333(with a rebate)

These super overclocked 4890 lose much of their value because they so closely priced to the gtx 285.
Additionally, he keeps on posting xbitlabs links, which writes very pro AMD reviews(which can be objectively proved), and uses a AA method(which no other site uses and they are criticized for it) which penalizes NV cards more.
Perkam a good guy, but lately, he been posting a little too much hd4890 stuff, some of it being misleading.
