Upgrading my graphics card and PSU questions

[Kyle20052]

Hello ladies and gentlemen.

I would like to upgrade my computer so I can run recent-newer games.

This is my computer model, bought off the shelf at best buy a few years ago (shame on me):

http://acersupport.com/acerpanam/desktop/2010/acer/aspire/AspireM3910/AspireM3910sp2.shtml

(Aspire m3910)

Processor: Intel® Core™ i7-870 processor (8 MB L3 cache, 2.93 GHz, with Turbo Boost up to 3.60 GHz, DDR3 1066 MHz, 95 W), supporting Intel® EM64T Technology, Intel® Virtualization Technology

Graphics card: NVIDIA® GeForce® GT 320 with 1024 MB of dedicated DDR3 VRAM, supporting NVIDIA® CUDA™, PhysX™, PureVideo® HD technology, OpenEXR High Dynamic-Range (HDR) technology, Shader Model 4.1, Microsoft® DirectX® 10.1, OpenGL® 2.1, OpenCL™ 1.0

(Genuine Windows® 7 Home Basic 64-bit if that even matters?)

PSU is one of these (I have no idea which) :
250 W (Non-PFC)
250 W (PFC)
300 W (Non-PFC)
300 W (PFC, 80Plus-certified, more than 82% efficiency)


Budget is under 200$ CAD.


A friend has suggested this combo:

with this PSU:

I would like to have your thoughts before actually spending money.

Thank you for your time!

Warning ncix did review on 4 gb of vram and it does nothing extra in certain instances and the price of card goes way up. 2gb is perfect but that grapics card is good too so ya for that and try this psu http://www.newegg.ca/Product/Product.aspx?Item=17-371-073

New warning your grapics card you friend picked is a pci 3.0 well your current one is 2.0×16 interface so use 2.0×16 when looking for a card and 2gb vram
