Recently my graphics card burned out and I am searching for a mid range card (sub $100) that can handle games like Cs source, WoW, etc. My brother suggested I get the Radeon HD 4670. I dont know much about computers and he says I have a PCI express x16 1.0 and that the card goes in a 2.0 slot but hes pretty sure it still fits. Will this work? Will it affect the performance of the card not being able to use the 2.0 slot? If it will not what would you suggest I get for a mid range card with my PCI-express x16 slot?
