AMD ATI Radeon HD 4890 Review

On the one hand I sympathise with the difficulty of getting all the elements of a comparative review lined up, but plenty of other review sites had 4890 versus GTX 275 ready on Day One.

But, as pointed out already, you've ended up comparing ATI's brand-new 4890 against the *old* model of the GTX260. Comparing it against the newer GTX260-216 would have been bad enough, but this is just totally meaningless. You conclude that a GBP 230 card performs a lot better than an old GBP 150 card. Amazing!

You really should have sat on this and done a proper comparison against the GTX 275. Or if you simply HAD to get something out, you should have done a non-comparison overview of the ATI and then followed up with the comparative review.

Last gripe (sorry): you say you'll do some overclocking tests when you've got the GTX 275. Meaningless. Fun, but meaningless. You surely know as well as I do that overclockability is a crap-shoot where one card of model X overclocks this much, but another identical model X overclocks to a totally different degree. The only overclocking it's worth reporting in a review is if it is guaranteed and under-written by the manufacturer (as does happen with some cards) Unless you can overclock say 20 randomly sourced versions of a card, the results from just one are not worth anything.

"...nothing revolutionary enough here to tempt me from my HD3870 :)"
"You do realise even the HD 4870 is significantly faster than the HD 3870?"

...not only faster...series 3 should be avoided.
