At least a few years, I hope.

I updated my system specs to the build I just ordered. (see below)

But now the store gave me a 2 week thinking period (since I have to wait for the parts to arrive), I m not quite sure anymore about the longevity of this rig. How long will it be relevant/high end.

Also, can future upgrades (a second gtx 560, new core,..) significantly improve performance later on?

They told me the GV-N560OC-1GI actually has a 560ti chipset :)

Yep, sure does. The Gigabyte card is powered by the ti chipset.
Oh and that Asrock board is great, have one myself. Stable and runs nice and cool. Running i7 2600k on this myself overclocked and temps are 34degrees CPU and 31degrees mainboard.
What CPU cooler are they putting in? And Case? Power Supply? Since they are giving you some headroom to change things, suggest posting all parts so your mind can rest as to your purchase.

Just updated the build.

Planned on getting the (cheap) Sharkoon case because of the big ass built-in fan on the side of the case. Just hope its big enough to house 2 gpus :/

Dont really have a clue how big those gpu's are...

ed: Thanks for already giving me some peace of mind. :) Those high end shots for us gamejunkies can really chomp rather large chunks out of one's wallet, hence the queeziness..

computer should last you about 3 years without updating anything. Around the 2-3 year mark (depending on your preference) you might think about updating the gfx chip but thats about it. The cpu should last you a good 4-5 years. You can't be certain about technology since it evolves so fast. But looking at the past, most cpu generations last about 4-5 years. I had my pentium 4 in 2003 and i continued using it till about 2010.

No system will play games at the high end for long. 1-2 years at max. Past that you will be looking at upgrading. Don't go for super high end parts in the hope that the system will be future proof.

The high end cards have a poor performance to dollar ratio. That means that 3 years from now that high end card will perform similar to the middle of the road card. Good choice on the GTX 560 Ti it has the best performance to dollar ratio of this generation.

Do not go SLI, multi GPU setups tend to have problems with microstutter and other issues.

The main problems I have with SLI is that even though it will increase your FPS you will think that the game is running at a lower FPS then it actually is due to one card rendering frames slower than the other in certain scenes. Multi-GPU setups tend to be a little less smooth than single GPU setups.

You just won't need the extra power right now. You usually are better off just buying a new card from the newest generation at the time that it starts to feel slow.

Thanks guys, thats some solid feedback :)

Now you mention it, on my current build I have 2 Radeon HD4850's in Crossfire, and I must say I almost never felt any difference in performance with the CF turned on or off.

I thought it was an ATI thing...

So getting a good one and replacing that in a few years time seems like a good tip!
