actually felows i wanted to buy the ASUS P5KPL-CM mobo
http://www.asus.com/products.aspx? [...] 3=563&l4=0
@ $51.5
NOT DG31PR mobo
http://www.intel.com/products/moth [...] /index.htm
@ $58.12.

because i 'v'e herd that ASUS are good coolers and performers BUT NEVER DID I HEARED THAT INTEL IS BAD, I VE SEARCHED THE WHOLE GLOBE BUT NO ONE- NO ONE DID RIGHT COMPARISION, THEY SAY INTEL IS INTEL... I SAY "WHY", NO BODY REVIEWS INTEL?

WELL the reason i choose intel because the vendor insisting that intel has better warranty than ASUS but they did not spoke clear about which one is better in performance, they said "we recomend intel... final choise is your's sir" PLS NOTE I BOUHT FROM THE BEST REPUTED DEALER/VENDOR OF MY ENTIRE COUNTRY.

SO WHEN I SPEAK TO GAMMERS hey say: ASUS
My vendor: Intel
Other vendor: Intel sometime ASUS for gaming

guys I AM REALLLLY STRESSED UP N CONFUSED IN THIS PLEASE ADVICE, IS MY CURRENT INTEL IS FINE, OR DO I REALLY NEED TO REPLACE WITH ASUS (FOR DIFRENCE/SOMETHING) IS IT REALLY WORTH IT because i did'nt find any prob with intel... is that ASUS board REALLY WONDERFULL?

--remeber i can't get any board exept intel/ASUS at my location (NO GIGBYTES!)

NOTE: please fellows GIVE ME CONCLUSION (chosse) ONE BOARD ONLY (from above two boards ONLY) WITH REASON(BETTER). Initially coment on boards only i l get ur wonderfull advices once my mind is made on board .

HEARTLY THANKS FOR SERVING UR IMPORTANT TIE ON THE ISSUE, THANKS AGAIN.

I Knw my frnd by bios opts u mean OCin, which i am not planing to do, the dg31-pr which i bougt is latest (rev10) with new heatsink design and 45nm support etc and in bios it does show all details (read Only) about temps and voltages, there are options of Graphics and all which are generally required, there is only one thing lacking which is OCin(which i WON'T DO). so dear is is any thing still worth considering to replace with p5kpl-cm as per above and any other criteria.? tell me one thing more my frnd are these boards able to perform for gaming and will they support hd4770 with all current sys specs for GUD gaming? pls review. and finnally advice whether shud i go for replacement or stay intel (pls refer to pc surrounding conditions above etc too).
thanx a ton budy.
