Upgrading both my systems

[Brew_WY]

So I am considering upgrading both my computer systems. One build is about 4 years old (my wife's) and my build is 2 years old. I list the system specs separately and what I was considering doing with them.

My Rig:

TWR: Cooler Master HAF X
MB: ASUS ASUS SABERTOOTH Z77 LGA 1155
CPU: Intel Core i5-3570K Ivy Bridge Quad-Core 3.4GHz (3.8GHz Turbo) LGA 1155
HS: Noctua NH-D14 120mm & 140mm SSO CPU Cooler
GPU: ASUS GTX670-DC2-4GD5 GeForce GTX 670 4GB 256-Bit GDDR5
RAM: G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900)
PSU:CORSAIR TX Series CMPSU-750TX 750W ATX12V v2.3 SLI Ready
SSD:SAMSUNG 840 Pro Series MZ-7PD256BW 2.5" 256GB SATA III
HDD:Western Digital WD Black WD1002FAEX 1TB 64MB Cache SATA 6.0Gb/s 3.5"

UPGRADES:
So I wanted to go SLI and add another ASUS GTX670 but Newegg just sold out of them about two days ago. So now I am thinking that I will maybe upgrade to a pair of these GTX 760's. I will also add another 8GB of RAM, some more case fans and a controller. I think I might start OC'ing my CPU also. I am primarily playing Darkfall: Unholy Wars.

GPU:ASUS ROG STRIKER-GTX760-P-4GD5 G-SYNC Support GeForce GTX 760 4GB 256-Bit GDDR5




Wife's Rig:

TWR: Cooler Master HAF 932 Advanced
MB: ASUS Sabertooth X58 LGA 1366
CPU:Intel Core i7-950 Bloomfield Quad-Core 3.06GHz LGA 1366
HS: Noctua NH-D14 120mm & 140mm SSO CPU Cooler
GPU: ASUS 5870 EYEFINITY 6/6S/2GD5 Radeon HD 5870 (Cypress XT) 2GB 256-Bit GDDR5
RAM:G.SKILL Ripjaws Series 12GB (3 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
PSU:CORSAIR TX Series CMPSU-750TX 750W ATX12V v2.3 SLI Ready
SSD:SAMSUNG 840 Pro Series MZ-7PD256BW 2.5" 256GB SATA III
HDD:Western Digital WD Black WD1501FASS 1.5TB 64MB Cache SATA 3.0Gb/s 3.5"

Upgrades:

She primarily plays Sims 3 and 4. I will probably add some more fans and a controller to her system also.

GPU: My old GTX670
RAM: Another 12GB of the same RipJaws

My biggest concern is that her PCIx 2.0 Slots won't be able to recognize the newer GTX 670 that is PCIx3.0 and I see this as being my only issue. Thanks in advance for any suggestions or advice.

It's backwards compatible.

To your rig, don't worry about the OC and just get a 970 instead.

To her rig, she doesn't need more than 8GB and she has 12. Give her your old 670 and she'll be set.

Will a single 970 really out perform a pair of 760's? I figure this system will last me another couple years and it will be time to build again. And if they are that much better, what about just going with a single GTX 980? Its a fair amount more money than a 970, and I am not sure the performance difference is there for $200. 970's are out of stock atm.
Thanks again for your advice.

 

[PP Mguire]

Be about the same give or take and the 970 will put off a lot less heat and sip juice compared to the 760s. You can also add another later as they'll get cheaper. SLI 970s make a nice powerhouse right now. I do not feel the 980 is worth the cost. If you want a 780ti Drogos will sell you a new Asus one for $350. Just PM him.

You in 'Murica? They definitely aren't out of stock here.

The ASUS 970's are out of stock on Newegg atm. I prefer ASUS as I haven't had failures with their hardware like I have with other brands. But I can be patient for now. Thanks again.

I'm sorry.

 

[Brew_WY]

I'm sorry.

Not a fan of ASUS I take it?

 

[PP Mguire]

Not a fan of their CS good sir, or their RMA department.

I personally LOVE Asus BUT there RMA dept. is pretty bad and difficult to deal with. Most things if faulty will go in the first month of use so stores like newegg.com give you 30 days for a RMA and after that you deal with the company. I'll go with ASUS on anything but the video card because that is the one item that get the most abuse with heat and functioning fans. EVGA has the best service with RMA and I'm now trying out MSI for video cards, My second one and have not had to RMA yet LOL. I only had to RMA ASUS to thecompany once and holy crap did I spend a LONG time on the phone with multiple phone calls and finally got a RMA number and they sent the same board back repaired. Not a new board.
