Looking to upgrade comp, need advice on GPU and PSU

Hi everyone just joined after lurking the forums and figured I'd get some advice,

I'm looking to upgrade my GPU to either an ATI HD 6850 or 7750.

My current pc specs are quite average, I have a Dell Inspiron 545 with:

Intel Pentium E5400 @ 2.7 Duo Core

300w unknown PSU (I know I will have to upgrade so a recommendation would be great)

7 gb DDR2 RAM

and my current GPU is the ATI HD 4350.

Thanks in advance!

  1. i would go for the 7750 because its more power efficient and your psu is not that great
  2. Do you think the 7750 would work with the stock Dell PSU? Also would that card be fine with my CPU?

    Just trying to cover all bases =]
  3. the 7750 will work 100% because it doesnt require additional 6 pin power connector for it to run. the 7770 for example requires the 6 pin power...with more power you get better speeds but you can visually inspect your power supply for 6 pin pcie cables

    your cpu will be fine
  4. 300W is pushing it and even then it's probably not the quality of a corsair or XFX, I would say you would be much better off buying a new PSU and it will last you much longer on the long run.
  5. 7750 without PSU upgrade would be the best I think.

    New PSU will open you up to more powerful video cards, but honestly, anything over the HD 7750 will be bottlenecked by your CPU.

    I used an overclocked HD 5670 in my Dell with the stock PSU (same as yours) for a year and it was fine - silent even. The HD 7750 draws less power than the HD 5670. I'd be surprised if your system + the HD 7750 draws more than 125w at load. And Dell uses good PSUs.
  7. the cheapest upgrade is to get the 7750 and stick with the current psu
    if you upgrade the psu you can get more powerful cards but at the same time you have a dual core. if you want to upgrade the psu get a 450-500watt and get something along 7850
  8. Ok thankyou very much for the information all, very helpful! :)

    Will have a look around for the 7750 and may upgrade PSU regardless to avoid any hassles, but will see how I go.
