Making a Gaming PC with a prebuilt plus parts ~$1000

Don't forget that you will need a new power supply. Get one between 500-600 watts from Antec, XFX, Corsair, or Seasonic.

Are Thermaltake Power supplies any good:

47.99 after rebate seems pretty decent for a 700 Watt Bronze PS.

hmmm, not the best.

Get something from the brands I listed above.

Rosewill HIVE series is also good.

One thing to remember is that the Gateway MB will not let you do any overclocking, and it might have proprietary drivers such that it won't work well with third party drivers.

YMMV!
Good Luck!

Seasonic is actually a original equipment manufacturer for power supplys and rest all are Brand names that brand their name on some other manufacturer. The part number describes everything.And so i suggest you should go with a Seasonic PSU.

And yes! your build is really powerfullll/_

Not sure why you'd go this route when you could build one yourself for around the same price. I could understand if you didn't know how to or if you simply didn't want to have to buy windows 7. Luckily I had a copy of windows 7 as I too am going to build a gaming rig and my budget was for approximately $800 - $1000. I did have a $50 NewEgg giftcard, and as of last week the power supply was $65 after mail-in-rebate. Regardless still paid under a grand... If your concerned with purchasing the OS simply remove the SSD and buy the OEM version of Windows 7 -> http://goo.gl/YgR8T If your hell-bent on keeping the SSD the build I've bought / listed below is still under $1000. Sure it's an i5 over the i7, but as far as I'm concerned the only advantage an i7 would have over the i5 is hyper-threading and that isn't even used by gaming.... I'm no expert, not even close. However, I will tell you that the number one thing I've learned is that prebuilt systems use s@#$ parts and I'll never buy one prebuilt again... Never had any luck that route....

Here is what I've ordered and am going mad waiting for...
