Hello,

Which graphics card is better? A GT 545 or a Radeon HD 6670?
I will be using this for gaming. I would like to be able to run Battlefield 3 at about 1280x800 - 1680x1050 with most options on low.

Nvidia GT 545

I am also up for suggestions of other graphics cards.

I only have a 305 Watt PSU and it needs to be a single slot (but I do have enough room for a large fan)

Update:
Okay so I think I'll be getting the Radeon HD 7750. But I only have a Core 2 Duo E6400 and DDR2 RAM. Will those bottle neck the HD 7750? If it does, would I be better off saving some money and getting a GT 545 or HD 6670?

Update 2: Seems like people think the HD 6670 is better than the GT 545. Does anyone know how big a difference there is between them?

Both are pretty slow. I would recommend HD7750. It's only 2% slower than GTX550ti, yet uses 27% less power.

Yeah I was watching a video of BF3 with the HD7750 and it looks pretty good. Do you think it will run okay with a 305watt PSU?

Yes, 7750 is one card that consumes very small amount of power. I recommend the 7750 too.

7750 is the best GPU you can get that will work with almost any PSU because it runs entirely off of the power supplied through the board.

Edit: Fixed the CPU model number

T6500 is a laptop cpu. Go to "my computer" and click system properties.

Ah whoops. I know its a Core 2 Duo and I think its 2.1 GHz, but I'll make sure when I get home later today.

Edit: Okay it is the Intel Core 2 Duo E6400

Yeah if it's 2.1ghz, your gonna need to overclock that puppy. Let me know maybe I can help you out.

Okay I found out the actual model number. Core 2 Duo E6400 - 2.13 GHz

You'd better off with 6670, except if you're going to overclock it to clocks like 2.75Ghz

Why 2.75GHz? If I overclock, will that take a lot more power from the PSU? if so will that leave enough power for the HD 7750?

The HD7750 uses less power than the HD6670 (55W vs. 66W).

305w psu and single slot card sounds like a Dell mBTX system.
If that's the case you won't be overclocking.

AMD has dominating the "best gpu for under 75W TDP" for over two years now. Started with the 5670, than the 6670 took over, and now its 7750.

6670 is better than the any other gpu than does not require a separate pci-e connector, besides of course the new 7750

I also think that the 6670 is about high as you can go with your cpu w/o running into cpu bottlenecks.
