Hi all,

A few years ago I bought a PC from Cyberpower and its been fantastic and working for me without issue, but I've decided I'm going to have a 3 monitor setup for Elite: Dangerous, so will probably need to upgrade my graphics card.

I've currently got a 660ti, and a Asus P8Z77-V LX motherboard, 600w powersupply and i5 processor overclocked to 4.2k mhz.

My questions are as follows:

1. Would it be better for me to buy another 660ti and go the SLI route, or would a 780ti be a better deal to outright replace the 660ti?
2. Considering my rig is overclocked, would me adding/removing things like graphics card affect the overclocking do you think?
3. How do I know if I'd need to upgrade the power supply from 600w to something higher if I were to get another 660ti or 780ti for example?

Many thanks for any and all help!
 
Well, first off you have a problem. THat board will support one Nvidia GPU, but it is a crossfire-compatible, so for more than one GPU, you need AMD cards, not Nvidia.

Is it that hard for you to read up the specs? it took me all of 2 minutes (or less) to Google the board model, and look up the specs on the Asus website.

Look under "multi-GPU support".

Well, its hard to read up on specs if I'm new to all this and have no idea what I'm looking for, yeah - Else I wouldn't be here asking the above 3 questions now would I? lol

So I'm gathering from your post you'd recommend a 780ti

Well, I think you should instead of using dual 660ti go with a single 780ti. There is not enough games utilize multi GPU setups, in addition your motherboard does not support SLI nor would your power supply. For the most part a graphics card swap should not affect the overclock on the CPU, and for the power 600w should be good as long it is from a decent manufacturer.
