Pros: GREAT OPERATING SYSTEM. ROCK SOLID. USING 64-BIT VERSION. IT ACCESSES MY 4GB RAM.

Overall Review: GIGABYTE GA-MA770T-UD3P MOTHERBOARD AMD Phenom II X3 720 2.8GHz @3.4Ghz/1.42V. ZALMAN 9500A-LED 92mm 2 Ball CPU Cooler G.SKILL 4GB(2X2GB)DDR3 1333@8-8-8-21-1T. ASUS EN9800GTX+/HTDP/512M GeForce 9800 GTX+ 512MB PC Power and Cooling S61EPS 610W Continuous COOLER MASTER RC-690-KKN1-GP Black SECC/ ABS ATX Mid Tower Computer Case WITH 7 120mm FANS

Pros: This card runs great. No problems of any kind. My idle watts are 115, with 7 case fans running. Full power with processor and HD 5870 under load are 310 to 360 watts. The average is 340 watts. I run milkyway@home and the ati gpu tasks takes about one minute and 26 seconds to complete. The 5870 runs at 59 degrees celsius with 100 percent fan speed. Great, Great Video Card.

Cons: I could have gone with an gtx 470 or 480 but the power would have been too high. high idle wattage also. So i can not crunch seti@home on the gpu. But the double precision floating point on the HD 5870 blows the nvidia away. Nvidia has limited the double precision floating point from one half of the single precision to one eight of single predision on the gtx 470, 480 series.

Overall Review: AMD 720 BE at 2.8 ghz with 4 cores running Gigabyte MA770T-UD3P motherboard G.SKILL 8GB (4 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 Western Digital Caviar Black WD7501AALS 750GB 7200 RPM 32MB Cache SATA 3.0Gb ZALMAN 9500A-LED 92mm 2 Ball CPU Cooler PC Power and Cooling S61EPS 610W Continuous, great power supply COOLER MASTER RC-690-KKN1-GP Black SECC/ ABS ATX Mid Tower Computer Case with seven case fans. Windows 7 64-bit

Pros: Works perfectly in Gigabyte GA-MA770T-UD3P motherboard. Just go into BIOS to set timings @ 8-8-8-21-1T for two sticks. You may have to use 2t timings. I am buying 2 more sticks and will recieve them next week.

Cons: This motherboard sets voltage at 1.6 volts. no option for 1.5 volts. however package says 1.5 to 1.6 volts, so everything is ok.

Pros: this is the first aftermarket case i have bought. i made a good choice. it come with 3 fans, 1 with blue lights and 2 without. i bought 4 dynatron 120 cm. 80cfm fans. i put 2 in the top as exhaust and 2 in side door as intake. i put a 80mm. x 25mm. fan in the backside of case. it does not fit but i forced the back door on with a bulge at the top of the door. it does not quite close. this fan size should be 80mm. x 15mm. nowhere in the documentation is the size of this fan listed.

Cons: very slight con but not enought to keep you from buying. the front cover is plastic and the snap on connectors are a little flimsey. everything about this case is well made and thought out.

Overall Review: a zelman 9500a fits with a fan in the side door. asus 9800gtx+ fits with room to spare. 2 inches at least. pcpac silencer 610 power supply has no problems. a asus a8n32 sli deluxe 939 motherboard is used.

Pros: good air flow with 4 of these in a coolermaster 690 case. helps keeps cpu temps at 41c max. the other 3 fans came with the case.

Cons: the noise does not bother me. the sound is a little high pitched and i perfer low pitched sound. however i put a vantec dampener kit on and it slightly lowered the pitch.

Overall Review: no problems with these fans.

Pros: nice color, fairly bright, fits well in coolermaster 690 case at the top and bottom.

Cons: the wiring is just long enough.

Overall Review: good choice for my case.
