oh, i thought OCUK stopped selling it a few months ago and i didnt check before posting ... my bad
and with the graphics, "light gaming" is mentioned (although i didnt take that into account earlier), plus i believe photoshop is starting to offload tasks to the GPU now ... dont quote me on that...
personally i go with "newer is better", as hd5 series = 40nm = much less power comsumption (yes im aware that in the low end it probably means about 10w if that, but every little helps right?).
having said that, ive just arranged the 4300/4600 tab by price, and look at what came out cheapest:

a mid range card that is cheaper the the low end card from the same series. Benralph , i think youve got your graphics sorted
