Best CPU for this MOBO.

I would get a whole new MB & CPU what would your budget be?

I don't think you need to spend that much how about this:

Intel Core i5-4670K Processor 3.4GHz $240 at NewEgg
ASUS Z87-PRO (V EDITION) $170 at NewEgg
I'd suggest getting some new RAM DDR3 1866 or 1600 8GB Kit

Well I don't know what VGA card your running but my system is similar but an older version and I've been able to run everything I play at max settings.

Jay Rich,

The i5 750 is a slightly odd CPU as it is an LGA1156, so as far as I know, no current CPU will fit it.

If you'd like to use the current motherboard, have a look at this chart >

http://www.cpubenchmark.net/socketType.html#id2

> which is a comparative performance list of LGA1156. At the top are LGA1156 CPU's that have performance significantly higher than the 750.

Unfortunately, the high performance versions of most CPU's can be quite expensive-used i7's 870's are about $90-100 i7-880's seem to be about $200+. The clock speeds of these are not much higher, but looking at the CPU scores, the performance of an 880 is 5681 as against the 3749 of the 750. Proportionately, that is a 50% increase.

As you've decided you would like to change the CPU, you must be dissatisfied with the performance and the task is one of how much performance improvement is useful to you as against the cost and fuss of a new motherboard and CPU.

Without knowing you uses for that system, if you have a budget of $1,000, I think you might as well sort of renew everything >

1. Intel Core i7-4770 Haswell 3.4 / 3.9GHz LGA 1150 84W Quad-Core Desktop Processor Intel HD Graphics BX80646I74770 > $309.99 (I suggest an i7 as they are hyperthreading and i5 is not)(The "K" version for overclocking is about +$30)

2. ARCTIC COOLING UCACO-FI11001-CSA01 92mm CPU Cooler > $22.99

3. ASUS Z87-PRO (V EDITION) LGA 1150 Intel Z87 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard > $169.99

4. Crucial Ballistix Sport XT 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model BLS2K8G3D169DS3 $154.99 ( 2 x 8GB allows RAM to be added later)

5. Western Digital WD10EZEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive, Blue > $59.99

6. EVGA 02G-P4-3753-KR GeForce GTX 750 Ti Superclocked 2GB 128-Bit GDDR5 PCI Express 3.0 Video Card > $169.99

7. SAMSUNG 840 EVO MZ-7TE120BW 2.5" 120GB SATA III TLC Internal Solid State Drive (SSD) > $89.99

Total =$977.93

The assumption here is that the i7-4770 uses less power than the i5 750 (95W) and that a new PSU is not necessary. However, a new PSU may be a good idea as new CPU's have subtle power saving modes and need accurate currents. If the budget is very strict, you might add a 550W PSU- Seasonic and Corsair are my favorites- and use a less expensive motherboard than Z87, which is one the higher performance chipsets, and shopping prices/rebates, can keep to the limits.

Again, this is a kind of generic idea to demonstrate how much $1,000 buys- almost an entirely new system of a quite high performance.

In my view, changing only the CPU may be a worthwhile stopgap to a new system, it's fast work, might only cost $100-$200 or so, and delay having a new system for a year or more, but only you can decide if the performance increase is suitable.

You should be able to run that GPU for awhile yet. DDR3-1333 isn't that much slower then DDR3-1600 so you can hold off upgrading RAM too if you like. You may need to reinstall your O/S if you have an OEM copy it is "married" to your old motherboard so you will need to get a new copy of an O/S.

if you can wait for it, consider waiting for a maxwell gpu. The i7 is slightly overkill and you will be well served by a better gpu instead

The i7 is overkill and Maxwell GPUs are NVIDIA's next line of powerful GPUs.

Even this would be a huge upgrade.

The i5-4670K is a very good choice if you want to pay $100 more for and i7 you can but the increased performance will not be that great. As for motherboards I prefer ASUS, Gigabyte and MSI over AsRock, but if the AsRock better fits your budget I'm sure it will be good choice. As to the Maxwell the new model is the GTX 750 and the GTX 750 Ti, what you have will use more power but it will run games better no need to change it for the Maxwell.

Just because I haven't recommended one all day. Non overclocking i7 performance.

Also the new Z97 chipset is out and that would support upgrade to Broadwell/Devils Canyon and for the latter you only have to wait till september or so
