PSU upgrade? Motherboard compatibility? GPU upgrade

Hello and welcome to the forums
1_Yes
2_In almost all games no
3_Yes,PCI-E 2.0 is backward compatible with 1.0

You should be good to go, sir.

Uh are these also compatible with my motherboard?

EVGA GTX 460 and an Toughpower XT 875W PSU. i know my CPU, RAM and motherboard are bad but i am planning for a future build next year Q1 2011 and would like to re use my PSU and GPU.

QUESTION 4:
The PSU says it has an "Main Power Connector (24Pin) x 1" is my motherboard 24 pins? (tried googling but can't find it on intel site ) What if it isnt? is it still compatible?

QUESTION 5:
Thanks Maziar about the info; PCI express 2.0 cards like the GTX 460 has backwards compatibility with 1.1 but what is the decrease in performance? Would i be at a significant disadvantage?


Thanks for your valuable time  

Your motherboard has a 24 pin main connector.. The PSU is apt to handle connections for a 20 pin main connector board also so nothing to worry about.. As for the PSU-GPU config, i'd recommend getting a GTX460 1GB along with a good 750W PSU such as the XFX 750W Black Edition or the Corsair HX 750W.. To talk about the differences between the pci-e x16 2.0 and pci-e x16 1.1 slots, the former carrier a higher bandwidth marking.. The current line of GPU's however rarely are able to flood the 1.1 slot bandwidth.. Thus it hardly results in a performance difference.. Your current CPU however is not so good to be used for serious gaming.. I wont use the term bottleneck here but the clock speed is less and you'll need to overclock for optimal results when using a card such as the GTX 460..

Your motherboard has a 24 pin power connector, and you won't see a noticeable difference between PCI-E 2.0 and 1.1
