PC upgrade help!

[RhodesW]

Hi, I'm thinking of buying a new graphics card and I have a few questions. I have an Advent DT2111 and my current graphics card is AMD HD6670. Will I be able to upgrade to an AMD 7970 because I'm unsure due to numerous sources saying that the 6670 is a smaller card. Also, will I need a new PSU and if so could you please make some recomemdations. And I would also like to inquire about whether any other upgrades would be worth paying for. Thanks,


P.S. I use my PC for gaming and like to play on very high/maximum settings on "intensive" games such as GTA IV. (I know that that particular games has issues on PC and is hard to run on any system but that was just an example)

Any other information is also appreciated as I'm the not the brightest when it comes to computers. Thanks again for any help offered.

Yes you will need a new PSU. Here's the one that I recommend you : http://us.ncix.com/products/?usaffiliateid=1000031504&sku=59615&vpn=P1550SXXB9&manufacture=XFX&promoid=1282.
Aside from that, everything will work. And yes, you will be able to run demanding games on maximum settings.

Thanks for your answer, I was unsure whether to bother upgrading as im not great with compatibility etc when it comes to PCs.
The link doesn't seem to work for me, i don't know why but i'll try and find one myself. Thanks again for the help,

thanks

also, would 550w be enough if i were to upgrade in the future or would i need a higher wattage?
thanks,

If you want to crossfire, it won't be enough. But for most upgrades it will be enough.

Sorry for asking loads of questions, but i was thinking of getting a new case as well to last me as long as possible.

I was thinking of the Cooler Master Cosmos II Ultra Black

I know that it is more than i will need and that it is as future-proof as i'm going to get but will i be able to swap cases? and how hard is it to do?
