Hi all. I have a £150 budget to upgrade my GPU; and I will most likely have to upgrade the PSU aswell.

The best pair I've found is the a 4850 & Corsair's VX 550W. However, I was thinking of a 5750 & Corsair's VX 550W.

Would you go for the 5750 due to DX.11? Also, would 450W be enough to power either of the cards, a Phenom x4 9650 CPU, 1 640GB HDD & 4GB DDR2 RAM.

Note: I won't be overclocking


Thanks.

If it is a quality 450watt like corsair's it will power it with either card

The 5750 performs the same as a 4850. But the 5750 supports dx11 and runs cooler/uses less energy.

A 5750 can run on a good 300-350watt PSU since it uses slightly less energy than a 4830. A 4850 will need a good 400watt PSU.

If the prices are the same or the 5750 is only $20 more than the 4850, get the 5750. If the 5750 is way more expensive, just get the 4850.

Yeah, I'll probably buy a Corsair PSU. Just wanted to check a 450W would be suitable.

Corsair 450W - £53.54
5750 512MB - £87.28
4850 1GB - £80.96

The 1GB 5750's are an extra £20 or so. Is the extra 512MB worth it? "Bang for buck".

5750 512MB - 4600MHz GDDR5, GPU 700MHz, 720 Cores.
5750 1GB - 1150MHz GDDR5, GPU 700MHz, 720 Cores.

512MB or 1GB?

I'd be plugging my budget into this:

Here's the "winners" from THG's latest (December) GFX Roundup
Best Graphics Cards For The Money: December '09

$50 - HD 4650
$65 - HD 4670 / 9600 GSO
$85 - 9600 GT
$95 - 9600 GT / HD 4830
$110 - GTS 250 512 MB
$120 - GTS 250 1 GB

$155 - HD 5770 / GTX 260
$200 - HD 4890
$240 - 2 x GTS 250
$310 - No winner (HD 5850 Honorable Mention)
$330 - 2 x GTX 260 / 2 x HD 5770
$400 - 2 x HD 4890
$410 - No winner (HD 5870 Honorable Mention)
$465 - No winner (GTX 295 Honorable Mention)
$625 - No winner (HD 5970 Honorable Mention)

"At $110, the 512MB version of this card offers respectable performance, and nothing else in the price range can compare to it. As fast as the Radeon HD 4850 and new Radeon HD 5750 (and notably cheaper), the GeForce GTS 250 has no real competition from the rest of the sub-$150 market at this time.

Bear in mind that going this route instead of the Radeon HD 5750 will cost you DirectX 11 support and Eyefinity. But in the context of gaming, you'll need to make other quality sacrifices long before trying to enjoy either value-add in the $110 range."


1 GB version of 250 draws 69 watts, 33 more than the 5750 and 26 less than the 4850

It is not worth the price difference.

A 5750 performs equal to a 4850, and won't be able to use 1GB of RAM.
