CF/SLI review incoming?
also you might want to check latest prices - the one suggested in the article @ scan isnt what they are charging today when they are on sale....
Will be waiting for better BF3 drivers and the Windforce/Frozr cards myself.
Nope, but it *is* what ebuyer are charging ;)Quote:

The Sapphire Radeon HD 7970 graphics card is available to purchase from scan.co.uk
how is the fact that it's £200 more for not that much of an improvement in performance not in the bad section ?
really need to see the XF results for 6970s, for £50 more you could get what, 40% more performance than tha 7970 ?
Because it's the fastest card out there. If value worked linearly then we'd all be using intergrated graphics or something - anything other than bottom end costs more than it gains you percentage wide. Add in early adopter markup and it's even more explainable. Just look at what's happening in the markets - people are actually willing to pay more than the original selling price to get one, hence prices are actually increasing.Quote:

My mates taking delivery of his Sapphire 7970 shortly then I can have my 5770 back and replace my 4770 I'm currently stuck with
Look at the benchmark results. The card is seriously under-performing on the Frostbite engine compared to all the other results.Quote:

That's true. Some people from AMD have hinted it's not a driver thing though - it's the way the engine is coded - a patch would need to come from Dice.Quote:

Using the 580 as a benchline in DX10 (I can't get DX11 to appear) it scored 60.3 FPS in 2011 at 1920*1200, and 41.7 in 2012. A factor of 1.446, which I can't explain....Quote:

I'm using the Iron browser, and no longer get that one. I get it every time in FF and infrequently in IE.Quote:

Well it's true and reasonable in both cases. For Bulldozer you've got a new type of processor that doesn't behave either as a pure full cores chip or as a combination of full cores and SMT, we've got modules that work differently. The way PCs are currently designed the OS is responsible for the threading, so either you have to go back a step and stop presenting cores to the OS (and thus applications) or you have to add a bunch of transistors to the CPU that has to gather up all the OS requests and re-sort them into better ways of doing it - that's a waste of transistor budget when it's something that can be fixed in software.Quote:

Again, maybe AMD *could* do some driver magic, but it's possibly too late by that stage, the calls from the game are the better place to fix it.
