fastest and best ssd under a hundred bucks

The SSD I suggested will meet you needs for Windows and some applications. I assume you will also recycle a HDD from your previous build as well.

I suggest you consider a better PSU in the near future. Yours is old and of questionable quality. Consider a Seasonic, Corsair, or XFX into your replacement plans when you can.

The GTS250 will be okay, but the APU on a FM2+ rig will meet your needs as well.

Understood. You should be good to go with the previously recommend Samsung then.

The SAMSUNG 840 EVO MZ-7TE120BW 2.5" 120GB, COLGeek has already given you a link to it.

I normally recommend Samsung ssd's. Samsung ssd's perform extremely well and they have a proven track record. Crucial, Plextor, and Intel are also worth considering. Lately the newer SanDisk ssd's have been coming on strong. Currently you can purchase a modern 3rd generation SATA 3 6Gb/s 128GB ssd for less about $80.00 or a 256GB version for about $160. Sale prices are right around $0.50 USD per Gigabyte.

Scroll down to the brands and models you are interested and follow the links to the technical reviews.

I agree with COLGeek regarding the Ultra power supply. Among veterans and enthusiasts Ultra does not have a rock solid reputation. The one thing Ultra had going for them was a patent for modular power supplies. I purchased their very first modular model just to try it out. When I turned it on there was a blue flash of light, a loud popping sound, and smoke. I exchanged it for a Corsair psu.

I just happen to maintain a PSU Lemon List that is listed in a sticky at the very top of the power supply section of this forum. It lists the psu's that have known problems. The problems are briefly described and a link is provided to a highly competent technical review with more detailed information about the problems. Here is the link to the PSU Lemon List:

Scroll down to the Ultra section and you'll what see kind of problems Ultra had in the past.

COLGeek mentioned Seasonic, Corsair, and XFX power supplies. They are all companies with excellent reputations for high quality power supplies. However, to be fair there are many other brands with excellent models. I maintain a PSU Recommendation List that is listed in a sticky at the very top of the power supply section of this forum. Here is the link:

Scroll down to the brands and models you are interested in and follow the links to the technical reviews. I only use 7 web sites that publish highly competent and thorough reviews. The reviews include extremely rigorous testing and taking apart a psu to identify components.

You mentioned the possibility of building an AMD APU based system. Have you read the reviews that were published this week? Tom's Hardware published a Kaveri review this morning. Here is the link:

http://www.tomshardware.com/reviews/a10-7850k-a8-7600-kaveri,3725.html

The Tom's Hardware review includes test results for such things as Adobe Photoshop products, productivity, compression applications, and media encoding and well as a comparison with a couple of Intel cpu's.

The build is under your maximum budget and you have a few dollars left over. I strongly recommend purchasing the Cooler Master Hyper 212+ cpu cooler. The APU is rated at 95 watts and has a high TDP for a modern processor. With the cpu and gpu combined onto a single component things might warm up. The Hyper 212+ performs well and is the best value for the money spent. It performs as well as cpu coolers that cost twice as much. The price is $29.99 and shipping is free:

The Hyper 212+ is currently out of stock at newegg. Just click on "auto notify" and enter your email address. Newegg will send you an email when the 212+ is back in stock. You'll also notice that there is a newer version, the Hyper 212 EVO. It costs $10.00 more and does not perform as well as the Hyper 212+. I use the Hyper 212+ exclusively in customer builds. I also use the 212+ in my two personal desktop pc's.

If you purchase the Hyper 212+, the new grand total is $369.95 which still leaves you under budget by $10.05.

Don't forget to start saving for a modern energy efficient power supply. Since you won't need a massive amount of power plan on spending about $60.00 to $70.00 for a high quality psu.
