I am building a new PC. Need Suggestions

well bro just wait more & get evga gtx 760 or 770-780 or titan & get i7 4k so more wait & get nice build better than lose money now & lose it again when you want to change , just wait & get everything good :)

Well what's your price range (and region)?

Get a gtx 670?It's still a beast

What's the CPU cooler? And you can get a better PSU.

Here are my thoughts:

1) You will do just fine with a 500W PSU, no need to go 650+ unless it is on sale. Look at the +12V rail, buffer about 10% extra amps to cover whatever video card you want to run and call it good enough. I'm running this 500W PSU with my GTX 680 and three SSD's without any problems.

2) You budget a 120GB SSD, but you probably only need an 80GB for most basic needs. Save another $20-$40 USD-equivalent scaling back your SSD, invest $10-$20 more and get a 1.5TB or 2TB HDD instead. More space on the main storage drive will give you better dividends in the long run.

3) What monitor do you have now? If you have one that's decent, but not quite as good as that one, I highly suggest waiting on the monitor purchase AND the GPU purchase. With the U.S. holidays coming around you're going to find some great deals--jump on a good video card once you can afford it, and buy a monitor once they go on clearance after the Christmas holiday. You'll save a small fortune while piecing together the build you want. Video cards and monitors are two components that can always be added later, as long as you have a suitable cheap model you can get by with until you make your big purchase.

Good luck with the build!

Do you want to overclock? If not, go for a xeon 1230 v3. It's more or less an i7 4770 without the igpu.
You'll get hyperthreading which will be usefull in future games. You know, 8 cores and such. The i7/xeon has theoretically 12 "cores". 4real/8 threads.
That will also be very usefull in autocad i guess. But remember, the Xeon doesn't have an igpu. You only need an H87 board for the Xeon as well.

If you think Hyperthreadig is useless, look at Crysis 3 benchmarks and compare the i7 against the i5 cpu's.

PSU might be a bit overkill. Get a gold 400-500 watt PSU and you'll be fine. This system needs 350 watt at max.
If you're planing on getting a second card though, you obviously need bigger PSU.

Bro, your build is perfect! Black Friday and Cyber Monday are here! You're set! Buy the 760! :D

Take WD Blue WD10EZEX

I keep seeing people going for the Samsung EVO Series SSDs, they are hopeless in terms of today's SSD market. Heck even the standard 840 series SSDs are better, but I would recommend the 840 Pro series, as it is pretty much 1st or 2nd out of all SSDs and isn't that more expensive (128GB for $110). Well worth it in the long run.

Hey, my suggestion is that you buy 2x8gb RAM, its pretty much the same price ;)

Thanks alot for all your help guys. I bought Asus MX239H IPS-LED monitor yesterday and i'll buy the rest in december.
