Is this Good?

I have a computer with a 300w psu and want to get a proper video card in it, i was thinking maybe a HD 6670 would do the job for me, http://www.ebay.co.uk/itm/AMD-ATI-Radeon-HD6670-2GB-PCI-E-DVI-VGA-HDMI-Professional-3D-Gaming-Graphic-Card-/261074344542?pt=UK_Computing_Computer_Components_Graphics_Video_TV_Cards_TW&hash=item3cc93e5a5e would this model be able to run games like battlefield 3 at 720p medium-high at around 60fps, or what is considered "playable" or would a 6770 be able to run off 300w? http://www.ebay.co.uk/itm/2GB-3D-AMD-ATI-Radeon-HD-6770-HDMI-1GB-1080p-3D-Gaming-BluRay-Graphics-Card-/121013698728?pt=UK_Computing_Computer_Components_Graphics_Video_TV_Cards_TW&hash=item1c2cfa80a8

PC specs:
Core I3-2130 (Max 65w)
8GB DDR3 RAM
ASUS P8H61-MX motherboard
1TB WD Caviar Blue
CD/DVD Writer

After a bit of research you really won't be able to run anything more powerful than a 6670 with such a low powered PSU. You might be able to play BF3 at 720p on low (maybe a bit higher) settings IF you want 60 FPS. If you are okay with maybe 40 FPS on High settings you would be alright. 6670's are not as efficient as the newer 7000 series or 600 series from Nvidia. If you want something stronger, a 7770 would also work on your power supply as long as you don't have any other power hungry components. Personally I'd go that route.

Get a 7750 GDDR5. Crazy strong for its price and power use. (~$105, uses almost no power).

which of these two models would be the superior one? http://www.ebay.co.uk/itm/MSI-R7750-Graphics-Card-ATI-Radeon-HD-7750-1GB-DVI-HDMI-DisplayPort-R7750-PMD1G-/121018659174?pt=UK_Computing_Other_Computing_Networking&hash=item1c2d463166 or http://www.ebay.co.uk/itm/1GB-MSI-Radeon-HD-7750-Overclocked-4500MHz-GDDR5-28nm-GPU-830MHz-512-Cores-/110959566496?pt=UK_Computing_Computer_Components_Graphics_Video_TV_Cards_TW&hash=item19d5b49ea0
I know the second one is overclocked but wouldn't that send the need for power even higher? and would it make much of a difference (sorry if I'm being annoying! :/ )

Would this one work in my pc: http://www.ebay.co.uk/itm/1GB-XFX-Radeon-HD-7770-Core-Edition-4500MHz-GDDR5-28nm-GPU-1000MHz-640-Cores-/110959567016?pt=UK_Computing_Computer_Components_Graphics_Video_TV_Cards_TW&hash=item19d5b4a0a8 ? And all the parts are listed and I don't think any of them are TOO power hungry I've only seen my cpu go up to around 50w was when I was rendering 720p HD video, because if this one would work in my pc it is between this and the 7750

Actually that 7770 might work fine. The 7770 could work on a 300w PSU, but it does need a 6-pin conneced to it. If your psu has either a 6-pin or a moled connector (Which would attatch to the converter that comes with the GPU), then you are fine.

As for the 7750's. I think those are both the same. Also feel free to over clock any 7750 as much as you want. It won't hurt your system.

OK thanks for your help guys! really apreciate it!

Ya, that 7770 should work pretty well. A little tip for the future: if you ever decide to build a computer, start with the power supply, it's the lifeline to all of the other - more expensive components. Best of luck!
