After quite a bit of searching ive come to realise im much better asking for help
The exact computer model I have is an Acer x3300 - 630
o Processor: AMD Athlon II X4 Quad Core
o Memory (RAM): 3 GB
o Storage Capacity (hard drive): 750 GB
o Operating system: Windows 7 Home Premium
o Shared graphics: NVIDIAGeForce 8200
Also here is the motherboard info:
Board: Acer WMCP78M
Bus Clock: 200 megahertz
BIOS: AMI P01-A3 08/10/2009
Im looking to get a graphics card that will run the majority of games at mediumish settings with a smooth frame rate, with the problem being the tiny case and the low psu (220-250w)
From looking my only options is to get a low profile graphics card.
Would these be powerfull enough cards and would a 220w psu be able to support them?
OR
Would I be better off buying a new case and psu?
Problem with this is that the motherboard is a micro-ATX, would getting a bigger case allow me to fit a card such as a HD 5770:

Or is the fact that its a small motherboard limit the graphics card I can install regardless of case size.
Would swapping cases be a problem since the pc is pre-built?
Also, would either of these suffice as a suitable psu to run the 5770.

Could anyone recommend a case that would hold a micro-atx mobo for >£50?
If you need any other info let me know.

Any help would be greatly appreciated.
Thanks.
