Im wanting to upgrade my current video card setup (2x 7800GTX 256mb SLI) to something newer along the lines of a ATI 4850 or Nvidias equal.

Is there much use/difference between the 512MB and 1GB cards ?

I am running an older system however so will be bottlenecked by the CPU more than anything - AMD FX-60 @ 2.6ghz and only have a 17" LCD @ 1280x1024.

TIA :)

I've got a 4870 1gb and my mate has a 4870 512mb, for us, the only games it really makes a difference in , is anything higher than say 1650x1080 with AA on, I play at 1920x1200 so it suits me fine :) his one starts having troubles at that res, even though he's got hte same card.

So I reckon 4850 @ 512 is perfect for you, especially at 1280x1024. I don't think you'll see much of a bottleneck with that res on that CPU, apart from running crysis in vista 64 with everything set to dx10 and very high :)

Um, round $45-60 each :) I'd say it'd be better to find an 8800GT for round $100-140 second hand and throw that in :) it's faster than 2x 7800GTXs and you could add another one in a few months for 40-60% more performance(in games that support SLI)

4850 is a killer card indeed :) easily overclockable too
I'm happy with my 4870, although so tempted by the 5850 and 5870 that just came out

I so need a new PC (sigh).
Been living off friends "old" systems which are better than what I had anyway heh...

Got the 7800's up on Trademe, fingers crossed they go and off to get a 4850 I go :)

Id love one, but the wife would kill me if I spent that much :-p
She's probably going to scream when I buy a 4850 on the sly :)

Also on my aging hardware, no point.....
