Radeon HD 6750 works for Dell Precision 390?

[azurewelkin]

I am currently planning to upgrade the ATI Fire GL V3400 card in my Dell Precision 390 Workstation to Radeon HD 6750.  Is there any compatibility issue that I should be aware of?  A lot of threads here seem to suggest that this could work, but I specifically want to make sure:

1) Is the 375W PSU sufficent?

2) Dell Precision 390's website below says that it supports up to 512MB graphics memory.  Should I worry since Radeon 6750 is a 1GB card?

3) Is my CPU (Core 2 Duo E6400 2.13 GHz) going to be the bottleneck?  Could this issue be better if I overclock it?

Below is the Radeon 6750 card and my current Precision 390 configuration.  Thank you!

Your PSU is good enough to power a 6750 but I would suggest going for the 7750.It's faster than the old gen 6750/5750 AND it consumes less power(55 watts to be exact).

No your CPU won't bottleneck.It won't be an issue but if you decide to O.C. it will only increase your performance even more.

Thanks a lot!

So there is no worry about Dell's website saying up to 512 MB graphics memory (as in my original post), right?

Lol.I totally didn't notice that you can scroll down.

Well what it lists is the different sku's for that model number.It's describing what possibilities can come with each package.It states that 512mb is the amount of VRAM that comes with the card in the PC(the one you already own).It also says right next to it that it can support up to a 150 watt card.

So you'll be fine.In fact you can go as high as a 6850.

I ended up buying 6770 which works fine for me.
