Performance drop after upgrade :(

Last response: in Systems

Okey!

So recently i upgraded my CPU, my Graphics card and my RAM. MOBO is still the same.
However, I don't really see any improvements in performance overall.

My old specs
MOBO: Gigabyte GA-MA790X-DS4, AMD 790X, DDR2, Socket-AM2+, ATX,GbLAN, 2xPCI-Ex(2.0)x16
CPU: AMD Phenom 9850 Black Edition Quad-Core 2.5 GHz Boxed, 4MB Cache, Socket AM2+, 125w
RAM: Corsair TWIN2X 6400C5DHX DDR2, 4096MB Kit w/two CL5 2GB Dimm's, E.P.P and DHX
Grapics Card: Asus GeForce GTX 260 896MB GDDR3, PCI-Express 2.0, 2xDVI/HDCP, 448bit


My new specs
MOBO: Gigabyte GA-MA790X-DS4, AMD 790X, DDR2, Socket-AM2+, ATX,GbLAN, 2xPCI-Ex(2.0)x16
CPU: AMD PHENOM II X4 965 BE 3.4GHZ 8MB SOCKET AM3
RAM: Corsair TWIN2X 6400C5DHX DDR2, 4096MB & Kit w/two CL5 2GB Dimm's, E.P.P and DHX HYPERX DIMM DDR2 4GB 800MHZ CL5
Graphics Card: SAPPHIRE RADEON HD7850 OC 2GB PCI-E DVI/HDMI/DP

Currently running on a 32-bit win7.

What could be wrong?
I'm thinking
1: Old drivers messing up the system?
2: BIOS needs to be flashed?
3: Upgrading to a 64 bit system?
4: My power supply is too weak? (Corsair Powersupply 550W Bulk, black, ATX/EPS, 120mm fan, 4xSATA, SLI)

Probably the hard drive. Hard drives weren't as fast as they are today when your computer was made, and hard drives are really slow today anyway. also they get slower and wear out with age. Buy an SSD or even a new 7200RPM Hard drive with plenty of space. If you have the money definatly go for an SSD, they are Super Fast and you WILL notice a difference :)  Thats if you install windows to it

1 - You need a 64bit OS to address all that memory

2 - Driver sweep for the older drivers

Try those 2 first the first wont do much for performance but will let you use all your memory, the 2nd may clear up issues (though if you install a 64bit OS the 2nd is done automatically with the format :)  )

Yeah, I was definatly thinking about buying an SSD. However, I found out that (if i understood it correctly) my MOBO only supports SATA II. Which means that if i buy an SSD the data transfer speed will not be much greater than what i have today: Samsung SpinPoint F1 750GB SATA2 @ 300Mbps.

Yeah, I'm aware about not utilizing all of my RAM, i need a 64 bit OS for that, which I'm getting soon. Hopefully after a clean install i should be seeing a good increase in performance. :)
