I've never replaced a graphics card before. I could use some help in the right direction.

I have a Dell Studio 540. Intel 2 Quad core @ 2.33 and 4gb RAM. The original PSU and my Radeon HD 5450 were replaced with a free PSU and a Geforce6200LE by a friend after they failed.

My power supply is 400 W, and it says 12v1 is 16A an 12v2 is 17A ( whatever that means ). Christmas is coming, and I would prefer to not have to replace the power supply AND graphics card.

I want to play WoW on high to ultra at 1600x900 at 30 FPS at the very least. I was happy with my 5450 when I had it, but that was also a couple of years ago and I now know after doing some research that I didn't truly have a gaming card.

I am looking at either the Radeon HD 6670 or the Radeon HD 7750.

Will my power supply be able to handle either of those cards?

Will they give me the performance I am looking for?

Is my CPU still good enough even though it is technically outdated now? Should I be worried about fitting those cards into my case?

Your system is a bit outdated, but it should handle a 7750 just fine. I don't know if you will get Ultra settings in WOW though. In order to get that (especially in more demanding games) you will need to build or buy a new system.

Thanks. I was able to play WoW on Ultra with the 5450, but that was 2+ years of technology and 2 expansions ago.

As far as actually installing the 7750, it pretty much just slides in the PCI-e x 16 slot, right? A tech-novice should be able to handle it?

Correct, it should not require a separate connection to your power supply. It's a pretty straight forward process (in this newb's opinion):

- Delete old card from device manager and uninstall any associated drivers
- Shut down, unplug pc
- Remove old card and install new card
- Reboot
- Install drivers for new card
- Reboot

Purchased XFX single slot 7750 core edition. Installed it easily and it's working fine.
It's handling WoW on high with 4x AA beautifully. Thanks for the help!
