Should I get two EVGA GeForce 9500gt's or one GeForce GT220 for running Crysis?

I was wondering which would have better for high powered games like Crysis or Call of Duty 4 if i SLI the 9500s vs getting just one GT220 since you cant SLI the GT220.|||i don't think that would provide enough power atleast for high settings hi res crysis, i have a gtx 470 and at max settings and 1920x1200 i get about 30fps|||I have used this product and it performs really well I would definitely suggest
