Just FYi the 5450 from what I see consumes 12W at load and the 6670 does 50W.

Yeah, like Goku says, "Requires XXXw PSU" isn't really what you need to look at. The better thing is to look up the card's thermal design point (TDP). And making sure the 12v rails on the powersupply can handle that much power (that's the rail's amperage times its voltage) + some margin for error.

What loads are we talking about here? Original StarCraft or BattleField 3?

If the latter, I'm surprised that thing runs at all - I'd expect everything to slow to a crawl.

Either way, you're going to need to pump more juice through that thing to give you a decent experience in PS2.

EDIT: Also, your 5450 has a TDP rating of just 19 W (Thanks to Rbstr for reminding me about that). The 430 has a TDP of 49 W while the 6670 is at 66 W. You might be able to get away with using this PSU instead but you should really consider giving it more juice than just 220 W that are in there.

Well now we are getting to the point of this upgrade costing too much given his current setup IMO. TheMozFather how about you salvage everything, but your case, PSU, and video card. Move everything else into a new case that will get rid of the low profile limitation.

I don't think you will be able to find a proper video card given your PSU situation is all.

You can do the following:
Asus HD 6770 1024MB GDDR5 PCI-Express Graphics Card - £74.39
OCZ ZS Series 550W '80 Plus Bronze' Power Supply - £49.99
Antec 300 Three Hundred Ultimate Gaming Case - Black - £44.99

Total = £183.47

With a 6670 for a cheaper build will bring it to £169.37.

For a performance difference between the two look here. Just look at the 5770 for the 6770 as they are both the same card.
