My current graphic card has just stopped working. I need to buy new card pretty fast. I've found GeForce® GT430 which fits in my budget (and has comparable performance to my current, silent GF8600GT).
I have rather old motherboard (asus p5kc, intel socket 775) which is based on Intel P35 Chipset. GeForce® GT430 specifications says that it is backward compatible with older PCI-Express slots but.. in requirements list it says clearly PCI-Express 2.0 compliant motherboard. I've found that Intel X38 was the first PCI-Express 2.0 capable chipset.
I am confused because I know that PCI-Express slots are cross comptabile but I am not sure if the requirement is just a "marketing requirements" or the card really needs additional wattage. I've also found that the card has 60W TDP.
