My 9500GT has held out surprisingly well for quite a while, but after getting Skyrim and barely being able to run it even on gimped graphics settings along with a load of other games, I've decided it's time to upgrade to something that handle new(er) games with decent graphics on medium-high settings. I'm thinking of getting a HD 5770 for about £85, but does anyone have any other suggestions? Would a HD 5750 perform similarly? I could get one for about £20 less.

Looking at the wikipedia list: http://en.wikipedia.org/wiki/Comparison_of_ATI_graphics_processing_units
The 5750 has a performance of 1008 GFLOPS, the 5750 has a performance of 1360 GFLOPS. So the 5750 is ~75% the performance of the 5770.

If it helps, my nVidia GTX285 from 3 years ago (got it on release day, when it was top of the range and bloody expensive) runs skyrim very very well and has a performance of 1062 GFLOPS, almost identical to the 5750.

I think I'll go for a 5750. I was impressed by the videos on youtube showcasing the performance of the 5770 on games such as Arma 2, Skyrim and Crysis, but the 5750 appears to do just as well and it will allow room in my budget for a better PSU if the current one can't handle a newer card.

My new video card just got here today....and I didn't take the time to verify my PSU was up to it first.

So really, depending on how old your PSU is, I'd start with that. There's this weird divide in cards where, up to a certain point, amperage wasn't really important, it was the wattage cards paid attention to.

In this generation, wattage is still important, but amperage is now far more important than it was before. So do your reading on any card you want to get and see what people are saying it wants; don't trust the manufacturer pages, they rarely mention shit like this. If your PSU is 4 or more years old, you might want to budget for a new one before you even settle on a card.

Because no one likes installing a piece of hardware only to find out it crashes your system, tear it out, replace the old part, and wait extra days for new parts.

My ATI HD 5500 Radeon could run Skyrim and TF2 on full graphics. I believe it's cheaper, but I don't quite understand how ATI numbers it's cards.

My PSU is a 450W (According to the side of the PSU) with 20A on the 12V rail. I've looked it up and people have said that with dual core processor, 2 HDDs and an HD 5750/5770, 20A will work fine. I've asked on other forums myself and it seems 20A would handle it just fine, and the power supply calculators seem to approve of the wattage. What do you guys think?

Processor: Intel pentium D dual core 820 2.8Ghz
Prospective video card: XFX ATI HD 5750 1Gb GDDR5
2 SATA HDDs
1 CD/DVD optical drive
4Gb DDR2 RAM
About 3 fans, 2 are probably 80 or 92 mm, another 120mm.

Edit: It should work, I've decided to buy it anyway.

Got it, but upon boot, there's no output from the card, the fan doesn't turn on and the computer powers itself off after 15 seconds. Probably PSU :/.

You should get the 6000 models, they are suppose to be cheaper and bit more powerful than the 5000s
