Performance of gtx560 TI OC in PCI-E 1.0 and 2.0

[Ram-01]

Hi ,
I want to buy GTX 560Ti OC.
I just have Dg31pr motherboard.It only has PCI-E x16.I think it would be PCI-E 1.0
But, the graphics card needs PCI-E 2.0
So,I want to know the performance of GTX 560Ti OC on PCI-E 1.0 and 2.0
I know card is backwards compatible but performance?
Please reply whether I want to upgrade motherboard also.

Hello and welcome to the forums
Well,the difference between PCI-E 1.0 and 2.0 isn't huge;however,judging from your MB,you seem to have a Core 2 duo/quad CPU.So if you have the money,then upgrading your motherboard and CPU(to something like Core i5 2400/2500) will definitely give you a huge boost in performance

Thank you, Maziar
What would be the difference if I use 400 watt power supply?
Please be more specific about the PCI-E 1.0 and 2.0.

I have Core 2 duo E7500.
2 GB Ram.

400W PSU? What brand? Type?
GTX 560 Ti needs 2 x 6 Pin power connector from PSU. Looking your 400W PSU, I doubt it has 6pin power connector.

What is your current card?

 

[Maziar]

The difference between PCI-E 1.0 and 2.0 is negligible(something like 5-15%)

GTX 560 Ti needs 2 x 6 Pin power connector from PSU. Looking your 400W PSU, I doubt it has 6pin power connector.

What is your current card?

At present I just have 300 W PSu.
I am going to buy Zebronics 500W SMPS will it suit the card enough?

 

[Maziar]

I recommend a PSU from a reputable brand such as Corsair,Coolermaster,Antec,etc.

Even the Platinum Series from Zebronics (600W) only provide 1x 6pin power connector, which mean you must use 4pin to 6pin molex adapter to run that card. Yes it will run but not recommended.
Isn't any other/better brand in your place? Just like Maziar says above, get a reputable brand like Corsair, Antec, OCZ, Seasonic, PCP&C, SilverStone, 500W is enough for single card.
