I have an older pc (HP P6270z) that has an AMD Athlon II x4 630 2.80 ghz processor in it (4 gb). When I first bought the pc I put a Radeon HD 4600 graphics card in it. This card has suited me fine. I am not a serious gamer by any standards, but have played all the Diablo games over the years and now have D3. While the game does run, I know it could be much better. My psu is a LiteOn 300W (PS5301-8hA).

I know the psu limits me but was looking at the Radeon HD 6750/6770/7770/7750. I don't mind spending $100-150 for a better card and the ones i listed run anywhere from $100 - $135.

I don't think I really game enough to replace the psu - so I would like to work with the restrictions I currently have if possible. Or is there any other cards I should be looking at?

The other thing that comes to mind is that i would also like to be able to switch back and forth between my dell monitor and a 40" led that i just got. I have purchased a long hdmi cable so i think im ready to go!


Thanks in advance for all your help!

The 7750 would probably be the best option here. It shouldn't need a new PSU and should still perform well. The 7750 usually performs between the 6750 and the 6770, although it does beat the 6770 in some games.

I would also like to recommend the 7750, but make sure it is the right version, as there is now a version that actually uses more power. To point out the different, you will notice one has a clock of 800mhz and one has a clock of 900mhz. The one with 800mhz is the one you want.

The 6870 uses like three of four times more power than the 7750 (0.8GHz). That would almost definitely mean that OP needs to get a new PSU along with a new graphics card and OP has made it clear that he doesn't want to do that.

The HIS and Sapphire are both the cheapest and they are still both great cards. The power cooler is more expensive, but it has a passive cooler (fan-less) that should be completely silent, so if you want to spend more on it, then it is an option too.

Sorry I don't mean to beat a dead horse, but would this one be ok?

ASUS HD7750-1GD5-V2 Radeon HD 7750 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card

It has great reviews (best of the 7750's) but it is a 820 mhz instead of the 800 you recommended and I wasn't sure if a 20 mhz bump would make that much of a difference?

Thanks again!

The problem with the 900mhz model is that it has an external power connector from the power supply, meaning it uses more than 75W. 820mhz really means the card is probably overclocked, and probably does not require a power connector from the power supply. That's all you need you look for when buying the 7750.
