I need to upgrade my graphics card, add some more RAM, and possibly upgrade my power supply unit and change case. The current system is noisy and gets very dusty so a case change appeals (though paying money out doesn't). I'm also adding an SSD, second 1Tb drive, and wondering if my PSU can handle it. Suggestions please!
What I have now:
Intel DX58SO Extreme, X58 chipset motherboard
Intel Core i7 920 Quad Core 2.66GHz ** Overclocked to 3.2GHz **
G.SKILL 6GB Tri-Channel kit (2GBx3) DDR3-1600 <- going to upgrade to 12GB
Samsung Spinpoint F1 HD 1Tb
XFX Radeon HD 4890 1GB 256-bit GDDR5 PCI-E 2.0 x16 CF Ready
OCZ 600W ATX2.0 Dual Rail 120mm Modular Power Supply
CoolerMaster Storm Scout ATX Mid Tower Black Gaming Case
For the power supply, I run two monitors (21" and 24"), a graphics tablet, USB keyboard, 2x USB mouse, and external HD through an eSATA port. I'm not sure if adding new GFX, an SSD and another terabyte drive to the system will push the PSU past its limits.
Any advice? Cheers.
