Hi,

I've decided to purchase a graphics card to be able to play current games at a decent resolution (at least 1280X1024), with a frame rate of at least 30 fps, but I'm stuck with deciding which one to go for. Here are the cheapest prices for each of the models:

PIXMANIA Radeon HD 5830 - 1 GB GDDR5 - around £155

Sapphire ATi Radeon HD4890 1GB HDMI PCI E HD 4890 - around £125

SAPPHIRE TECHNOLOGY Radeon HD 4870 - 1 GB GDDR5 - PCI-Express 2.0 + CG-211E DVI male / VGA female Adapter - around £95

I would like to be able to play DX11 games, but I do not consider it necessary at the moment. My concern is, by the time DX11 is implemented in most games (if not all), would the 5830s still be up to the task? Therefore, is it worth spending £30+ for a GFX that generally only matches 4890s in performance (unless I'm sorely mistaken) with DX11 capabilities?

Secondly, what is the general performance difference between the 4870s and 4890s? I have heard that the 4890s are just OC'ed 4870s, so is it worth the £30+ premium for this performance difference? In addition, how large is the performance difference between the 1GB and 512 MB models of the 4870s?

Thirdly, is there much difference in performance between the same models according to the manufacturers? Is there any manufacturers I should avoid?

Lastly, my current setup has an athlon II X4 630, patriot sector 7 1600MHz 4GB RAM, and a 600W OCZ modxstream PSU. Would I be noticing a large difference in performance between these cards under this setup? Would any of these cards be overkill for this setup?

Thanks in advance!

Actually it is, particularly when new driver make it perform at least as good as the 4870.

HD5770...
New tech, less heat, less power consumption, dx.11 capable, good for a long term...

Thanks for the quick replies.

With regards to darthpeggie's post, do you mean that for now the 5770 can only match the performance of the 4870's until the new drivers arrive, or have the new drivers already surfaced? Also, at around £120, can it match the performance of the 4890s considering the 4890s are only around £5 more?

And also, would the 5770 actually be capable of running games at a good enough resolution and framerate by the time DX11 becomes mainstream?

Yes, HD4770 will be enough for 1280x1024, but HD5770 offer newer tech and good for long term...

I'd say 4870 value for money or 5770 as it has DX11 and is more future proof.
