Can't beat an HD4850 at that price point.

With your budget the 6850 at $139.99 is a good buy.

25 bucks more at $175 you can get the 6870

Here's the benchmarks if you'd like to see that too.

Personally, I prefer NVidia so I'd get the 560gtx and oc it on that budget at $169.99

Its pounds not dollars

Have you used online retailers in the past, if so would you mind posting a few of them that you would consider ordering from.  This will allow those of us who are not familiar with the cost of GPU's in your country better assist you in offering advice that makes sense.  I realize I could simply calculate the Pound to Dollar amount and then offer advice but through converations I have seen on this site it's become pretty obvious all costs are not equal when it comes to computer parts.

No i have never used a online retailer to buy comp parts before, although i am familiar with some. I do know that newegg is no good to me as that don't deliver outside of north amreica, I'm in the UK.

Both of these sites were recommended as the closest the UK has to Newegg.

I'd recommend you check out what is available then decide on something you like.  Afterwhich you just pop it into google followed by review and check out what the professionals and users think of the card.

A quick glance appears you have the AMD 6850 or the Geforce GTX 560 Ti at the top of that budget (the 560 Ti is slightly over)

I'm not sure what you mean that your existing card just about fits on your motherboard.  Usually the question of whether a video card will physically fit is one of card length, and the problem is fitting inside the case.  For this, the PCI Express x16 connector on the bottom of the card is the same on every modern gaming card (including yours!), so you can use that to gauge the relative length.

There's also the question of power consumption, which is both about how much your current power supply can safely deliver, and also about how much heat your case can safely dissipate.  If those aren't concerns at all for you, then the fastest card that you're going to find on your budget is a GeForce GTX 560 Ti:

http://www.overclockers.co.uk/showproduct.php?prodid=GX-173-OK&groupid=701&catid=1914&subcat=1810

I'm guessing that the heatsink and fan on that one will be barely adequate, but nothing more, so you'd better have a good case if you're going to stick that inside.

The next step down is a GeForce GTX 560 or Radeon HD 6870:

http://www.overclockers.co.uk/showproduct.php?prodid=GX-143-MS&groupid=701&catid=56&subcat=1866

http://www.ebuyer.com/269172-msi-gtx-560-1gb-gddr5-dual-dvi-mini-hdmi-pci-e-graphics-card-n560gtx-m2d1gd5

They perform comparably, while the 6870 uses less power while being cheaper, so I'd lean toward the 6870 if you're choosing between those two.

If you want to pick something smaller that your case and power supply can definitely handle, then a Radeon HD 7770 fits the bill:

http://www.ebuyer.com/370438-powercolor-hd-7770-ghz-edition-1gb-gddr5-dvi-hdmi-displayport-pci-e-graphics-ax7770-1gbd5-dh

Performance will be a little shy of double your current card, while using less power.  As you can see from the card barely extending past the PCI Express connector, it's a small card, too.

If you're inclined to stretch the budget, then the next step up is a Radeon HD 7850:

http://www.ebuyer.com/385789-msi-hd-r7850-twin-frozr-oc-edition-2gb-gddr5-dvi-hdmi-dual-r7850-twinf-2gd5-oc

That will be the fastest card that I've linked, though it's not a huge advantage over the GeForce GTX 560 Ti.  It will also use the least power of any card I've linked, other than the 7770.  That's the fastest card you can get that only needs a single 6-pin PCI-E power connector, like your current card.  The Radeon HD 6870 and GeForce GTX 560 and GTX 560 Ti all need two 6-pin PCI-E power connectors, which your power supply may or may not have.

I have a ANTEC 900 case, the one with the blue lights and 700W power supply

Your case can readily handle any of the cards I linked, then.  Exactly which power supply do you have?  The nominal wattage doesn't mean much by itself, so I'd like to see the exact brand name and model.

The power supply is decent but not great--but most importantly, isn't bad, either.  It should handle any of the video cards I've linked above just fine.

Thanks for the help, i think i'm gonna go for the HD 6870

I have been sticking with ATI / AMD video cards for some time now. I found Nvidia to have a grayscale issue in 2004, since then, never tried Nvidia again.

Curious to know if that is still an issue.

Nvidia are a rip off in the UK, AMD are way better value in the UK.

Example 7870 which is same performance as 580 is cheaper than a 570

Which doesn't do you any good on a £150 budget.

For the price range it really is the best option (GFX performance wise anyway) and it's what I currently use (SLI but even when I have to turn SLI off I still typically get 50+ FPS on all currently released games at max settings 1920x1080).

Ignore this
