I'm looking to build a desktop for gaming for around $700-800. I planned out a build on pcpartpicker http://pcpartpicker.com/user/arakuto/saved/2B4T and would like to know how quickly it would become obsolete. I'm also wondering if it's worth an extra one or two hundred dollars to get an i7-3770 processor(I also do some CAD work and rendering) and gtx 670 gpu instead. Thank you!

The PSU you've picked out is not very good quality. It only puts out 25 A on the +12V rail, which means 300 W max. With just your GPU and CPU you are coming dangerously close to the maximum power output of that +12V rail, and you definitely would have to forget about any overclocking.

I would suggest picking up another brand, like Corsair or Seasonic, and specifically checking amperage on the +12V (take amperage, multiply it by voltage - in this case 12 - and you will get wattage). The most important (and power-hungry) components in your PC - including CPU and GPU - will use the +12V rail, so it is crucial to check if that rail can handle your power requirements.

Also MSI motherboards have been known to be kind of flaky. I would go...

The 8350 should be good enough for 3d modeling/rendering. There's no need to get a 3770.

Looks like a good build, my guess is that you already have the RAMS, so no point in advicing to buy any.

Its a good build, and as far as buying the i7 dont, its not worth the money.

The fx8 is better for CAD rendering (i know from personal experience) and its just as good for gaming.

edit:That PSU IS BAD It is considered a tier 5 unit, so do not get it. Having a bad cheap PSU pontetialy damages your build.

Be sure to get at least a 550/600W from brands like Seasonic, xfx, corsair, antec.

First off, looks like you've got a solid start with that build. CPU-wise, an i7 would be significantly better, particularly since hyperthreading offers a noticeable performance improvement in multithreaded programs like CAD environments. That being said, the issue of whether it's worth the extra money depends more on your other uses and budget. The FX is a decent processor which should be more effective in coming years as more programs are optimized for more cores. In general, NVidia GPUs are better options for CAD than AMD due to their CUDA cores (don't know a whole lot about the reasoning tbh, but I've heard it a number of times from friends who CAD.) The equivalent of a 7870 is a GTX 660, but a 760 is a good choice as well. The 670 you mentioned is fine, but 700-series cards have better performance/price. On a side note, the power supply you have listed seems questionable; if you get a 550W, make sure it has a high efficiency rating and choose a well-known brand like Corsair. Overall, the lifespan depends on intended uses as well. If you're gaming in addition to CAD, a GPU upgrade every few years is never a bad idea. If you do CAD only, I don't see any reason you couldn't get 5+ years out of it without needing upgrades.
Anyway, good luck with the build.
