Bring out the table

02 There's little point in HEXUS reiterating what's already known about GeForce GT200, so please head on over to our in-depth architectural look to refresh your memory.

However, it's always worth reeling out the Table Of Doom for a 'new' SKU.

* estimated pricing for a stock-clocked card.

We've included the major discrete graphics cards priced at over £150 - three from NVIDIA and two from ATI/AMD.

Place particular attention to the columns listing the vital stats for the GeForce GTX 260 GPUs, both present and new.

Clock speeds remain identical, meaning 576MHz for the core, 1,242MHz for the shaders and 1,998MHz for GDDR3 memory.
