I don't know which to upgrade, the GPU (possibly the PSU too) or the hard drive. My PC is running pretty slow, even for web browsing. But this PC will be mainly used for Photoshop and video editing. My current setup is :
Intel Core i7 3770 @ 3.4Ghz
AMD Radeon HD 7570
Western Digital Blue Caviar 7200rpm 1Tb ( possibly to Samsung 850 Pro 512 Gb while keeping the original one)
10Gb DDR3 RAM
