Upgrading my OC desktop for the Oculus Rift advice

[bolo_bokn]

Hi all,

I purchased my current desktop from OC in January 2014. It's been great, but I have a pre-order for the rift and am aware that I need to upgrade to meet the minimum spec.

This is what I own at present:

"Titan 420i Tanto" Intel Core i7 4770K @ 4.1GHz Overclocked

Haswell Quad Core Gaming PC

GX-182-GW Gainward GeForce GTX 780 Phantom 3072MB GDDR5

HD-168-SA Samsung 250GB SSD 840 EVO SATA 6Gb/s Basic -

CA-129-NX NZXT Phantom 530 Full Tower Gaming Case - Black

SW-165-MS Microsoft Windows 8.1 64-Bit DVD - OEM (WN7-00614)

CA-048-CS Corsair Builder Series CX 600W V2 '80 Plus Bronze' Power Supply

-----------------------

My questions are:

1. If I want to upgrade to a GTX 980 TI, do I also need to upgrade my 600W PSU? I have a feeling it may be too weak?

2. Do I need to upgrade my 8GB RAM?

3. Should I hold out for a couple of months to get a GTX 980 TI cheaper?

Thanks in advance for the advice!

Thanks very much for the replies.

Is it easy to switch out a PSU and replace it if necessary? I've never done it before.

Also, what would happen if the PSU can't handle the new GPU?

I want to get everything that needs upgrading done when the rift arrives, so I am good for at least the next couple of years.

I am only mildly experienced with tinkering with the innards of a PC (GPU and RAM).

So i'll wait to upgrade the GPU closer to the time of release - Thanks for the advice.
