Upgrade or build anew?

[kexin]

I have the following in my current build:

Asus M4A77TD Pro AMD 770 (Socket AM3) DDR3 Mobo
AMD Phenom II X4 Quad Core 955 Black Edition "125W Edition" 3.20GHz (Socket AM3)
GeForce 9800 GT 512MB
Corsair CX 400W ATX PSU
10GB ram


I have had this for a few years, and planning on firstly changing the GPU and PSU for something better
I had been looking at the GeForce GTX 650 Ti, and getting a psu at around 600W+

I am an avid gamer and from time to from enjoy a little 3D modeling on 3dsmax

After seeing around that the GeForce GTX 650 Ti I have looked at at some stores that the PCI-E is 3.0
I wasn't sure if my mobo would support it nor could I find anywhere else that had covered it.

Could anyone give me any advice?
I intend to use my pc for gaming, likely to the high end of MMO gaming.

Is my mobo ok to keep or should I change?
or should I work with a new mobo/cpu/gcu/psu altogether?

A pcie 3.0 card will work in a 2.0 slot, although if you want to spend alot(and have an amazing build) you could upgrade your mobo/cpu/gpu/psu, it all comes down to how much you want to spend.

Ask me if you want to know some good parts to upgrade to.

Once you started upgrading the only thing you would keep was the case and the os. I would think whether I had a use for the old computer as is (like a HTPC or a file server) then start budgeting for a whole new computer.
