Fantastic Purchase

Previous motherboard died therefore had to buy a replacement.
Happy with product performs extremely well, have my Q6600 clocked at 3.2Ghz
Really nice features included in motherboard's bios(s) - YES it has 2. Internet browsing/ skype calls/ image browsing etc. The Bios is bullet proof, and will revert to default values from the second bios if the pc cannot successfully boot. Fantastic board with plenty of SATAII ports, great for raid configurations.

Rock solid

I bought one of these boards a while back from Overclockers and all I can say it's fantastic! It handeles very high FSB with no problem. I have my E8500 Core 2 Duo running at 8x550 FSB = 4.4Ghz rock solid!!! I'm on air cooling. 3dMark Vantage Performance test with GTX 295 is over 21000!! Who says LGA775 is dead???? 5 stars!

500+fsb quad (If you're lucky)

This is an excellent board, I've got the p5q-e which is almost identical to the deluxe (bought from overclockers) and a watercooled G0 q6600. It runs 475x8 stable (prime95 and linX) and has hit 513 fsb for a cpu-z validation. In my experience, if you're looking for a board that will get the most from your processor, both the deluxe and the -e are great boards to buy :)

Perfect Board

This board is one of the best boards I've had. Clocked my Q9550 right to 3.4GHz with out changing any volts. perfect stability. I highly recommend this board.

Jeremy 2010-09-11

Overclocking made easy

Excellent overclocking board that maintains stability when overclocking any socket 775 chip, minimising vdroop and vdrop through excellent load line calibration. I would recommend this board to anyone trying their first overclock or looking for a solid, reliable ASUS product.

No problems with installation, fitted in Antec 902 like a breeze.

Quality product and very pleased I went with overclockers for the purchase.

Well yeah but no

Amazing Motherboard, died on me after a couple months for no reason. Taking it out my case i managed to void the warranty.


one word.

Back to my abit thing >.>

Great Buy

Just got this MB along with 3.0 ghz intel duo, 4gb 1066 dominator ddr2 and the nvidia 896mb overclocked 260, what can i say im very impressed!

The epu 6 engine gives you easy control to all the fans and power supply to your unit at the touch of a button.

Currently im running only 2 chassis fans (1 at 2000 rpm/1 at 1400 rpm) along with the stock cpu/gpu fan and this thing off load will run at 22c easy! The heat sink pipe along with this has got my cpu at 16c off load! truely amazing considering once im running sli and start to overclock with the H50 liquid cooling the margin to overclock will be impressive to say the least.

The easy power button on the MB itself comes in handy as well when you set it up, not to mention it does look pretty bad ass in the unit once its all fitted :)

Average gamer or overclockers this is a recommened buy for the price.

Great Motherboard

Bought this MB for my little brother's PC and he has on it a E8400 @ 3.6Ghz 4GB RAM @ 1100Mhz and 2xXFX HD4830 and the board performs excellent.5/5.

Another great asus board

Been using this board now for 6 months with no issues, easily overclocks my water cooled Q6600 to 3.4GHz with no hastle, only 38 deg with full load on all cores. Running 8Gb of PC2 8500 ram at 2.1v again with no issues, loads of OCing options to satisfy any serious user. Also been using Windows 7 Beta and now RC with no problems, highly recommeded socket 775 Motherboard.

Sparky 2009-10-22

Great mobo

nice bios settings easy to overclock hasent crashed once on me it also has a 6 different power options you can have for your motherboard saves your electric bill if you put on auto mode it know if your playing a game or not totaly stable totaly recomended running mine on a e8400 at 3.00 Ghz, 4 gb ram and a 250 gts 1gb version having no problems at all worth the money :)

Troy Carr 2009-10-10

Easy Overclock

I've had this board for 8 months now. Intuitive BIOS. Very easy to overclock your CPU. My Q9550 is running happily at 3.4ghz. I'm sure I could push it further too.
