I have a Dell 9200 .. 4GB RAM
Intel core-2 Duo 2.4GHz
It has an nVidia Geforce 9600 GS 256MB

Running W7 32 bit

Since I started editing HD video found that PC can't keep up with rendering and processor flat lines,
I intend building a new PC at some point .... as an interim if I changed to a faster Graphics card now would that improve things .... hoping if graphics work was hived off the GPU then PC will be fast enough.
I use 2 x HDD and having paging files and apps set on separate HD to OS

I don't use it for gaming ....
Photoshop picture editing (and no problem there)
Video editing HD video ... this is where it struggles.
It was OK on non HD, but 1080p is showing it's limitations.

If so any recommendations on what Graphics card to get, I would then aim to use that card in new PC when I build one.

Hey Osprey

Well whats your budget?
and whats the wattage of your computer?

It usually comes with the needed wattage to power it up and work on it, if you are upgrading video card, then you'll probably need a new PSU.

The 9200 has a 375 supply

It works happily on all except HD video

With 375W... You'll need to upgrade the Power Supply...

I ask again, Whats your budget?

You could get this

Graphics card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130661

I don't have a budget, but will pay for a good value for money config for new machine.
I'll build a complete m/c and donate existing one to the family.

Which usually means don't go for latest gen of things ... as I am not into gaming.

I think a ASUS Motherboard coupled to an i5 CPU with 8GB RAM is my starter config.
Maybe of 3rd gen Intel i5 3570 ( 3.4G 6MB ) Ivy bridge ..

What would be a good match of motherboard and graphics card ?
ASUS Radeon HD 7770 is my thought for Graphics .... not sure about a matched MB though poss P8Z68 ??

I'll also put in an SSD for the OS and maybe 2 x SATA in a Striped RAID config for data & apps, or maybe I won't need that with the SSD.

Welcome reconsiderations.

This would be my setup, some other tech members may disagree, or remove some components and put other.
But they are free to post their suggestions

Thanks for the effort ...
Couple of Q's ... you show the ASRock MB, I had been looking at ASUSP8Z77-V Pro ... any pro's/con's regarding that MB ?

With the SSD ... assume that would then be C:/ for the OS ... and apps & data off onto the HDD

There are no big differences, but you should go for the ASUS

Yes, the SSD would be C:/ The OS and programs
The HDD would be D:/ and that would be for any type of storage.

Thnx ... appreciated.
