Hello , i have a tight budget mainly constructing gaming pc so i went for AMD based , was thinking of Athlon II x3 445 or phenom x2 555BE , but i heard with both of these its possible to unlock +core , im not into overclocking ( no expierence), so if i go for x3 445 to unlock core i need a better MB that supports UCC right ? or i can go with phenom with stock ghz or stronger CPU and get cheaper MB , i need your advice becouse im in pickle here , and im prolly gona be using saphire 5770 or gtx 460 will it /not bottleneck ? .Thanks !
