Will my mother board support Nvidia GT640.

I'm confused about the PCI 3 support for this card.

Will my mother board support PCI 3 graphics card?

Yes it will work fine. All PCI-e 3.0 x16 cards are backward compatible with older PCI-e 1.0/2.0. Although do be sure that it won't interfere with anything you have plugged into PCIe x1 slot.

I have a 450W SMPS, Core2Duo 2.2 Ghz, 4 gigs of RAM and current GPU is GT220.

I guess the GT640 uses 350W?

Hope mine SMPS is poweful enough to support this GPU.

I do have one more question here: Will my motheboard support DDR5 GPUs?

The memory on the card has no relation to the memory used on the motherboard.

eVGA lists a 350W PSU w/ 20A available at +12V as the minimum requirement for their GT640 cards. The card itself is supposed to use less than 65W. (It has no auxiliary power connections, so it would be 75W or less to stay within the PCI-E spec.)

You may wish to check the label on your PSU to see whether it can do the 20A. For example: this one:

RAIDMAX:: RX-450K

is nominally a 450W PSU, but it offers only 21A at +12V. That's really poor for a "450W" PSU, but it's still within the requirements.

This is the tab column on my SMPS:

I cant understand a bit of it. bobkn@ is it enough for GT640 graphics card?

If you rely on eVGA's requirement, 20A (Amperes) at +12V, not quite. Your PSU offers a maximum of 18A. That's very weak for a "450W" PSU, unless it has more +12V rails than you list.

Your PSU is almost certainly adequate anyway. I'm not sure which Core2 Duo 2.2 GHz CPUs you have, but the most power-hungry one that I find (ARK | Intel® Core) is rated at 65W. If the eVGA spec is written to cover CPUs that consume a lot of power (125W), then derating their requirement for the CPU that you actually have would translate to about a 300W PSU that can deliver 15A or more at +12V.

I'll leave it to others to warn you about the risks of cheap power supplies.

bobkn@ that's the exact CPU i have, e4500.

After a bit of more research, i found that HD7750(almost same rate as GT640) out performs 640.

I was willing to go with: Amazon.com: EVGA GeForce GT 640 4096MB GDDR3 Single Slot, Dual DVI and mHDMI Graphics Card 04G-P4-2647-KR: Computers & Accessories

but now; I'm considering: Amazon.com: ASUS HD7750-1GD5-V2 AMD Radeon HD 7750 VGA 1 GB GDDR5 Graphics Card: Computers & Accessories

Hope DDR5 isn't an issue with my MB(as stormy13@ mentioned).

We do have a DDR3 version of it: Amazon.com: Gigabyte AMD Radeon HD 7750 2GB GDDR3 VGA/2DVI/HDMI PCI-Express Video Card GV-R775OC-2GI: Computers & Accessories

Not very sure what GPU to purchase. Also, I will more like buy a new SMPS for this new GPU.

Your inputs would be appreciated.

TIA!
