The other posters forgot to mention that the 650 has 128 polyphony and the 640 only has 64 polyphony. This is good for more technical music pieces in that the more polyphony the less chance of a note dropping off.

There are 4 main New Features for the DGX 650 over the DGX 640. These include the STYLE RECOMMENDER (helps you find appropriate backing track (drums etc.) based on the rhythm of a song you are playing), AUDIO RECORDING - the ability to record audio in WAV format (not just MIDI anymore!), SPEAKER OVERRIDE (can route keyboard through sound system and keep the sound coming out of the keyboard speakers also so you can use the keyboard speakers as your monitor). This is very important to me, and AUX INPUT (play along with an MP3 player). --BB

Hello- think of the Honda Accord. Every few years, Honda comes out with the "new" Accord however it is only every 6-8 years that the company changes the look. So this year, Yamaha changed the look for the DGX640 to different colors. From blonde & brown to black and white but the electronics are the same I believe with maybe one or two minor changes such as a new voice. Best, Andy's Music

I think that the difference is the hard drive in the 720. If I compare the specifications from both players is that the only thing I have no experience with the 720 but own a 700 and is working fine

The GTX 650 video card used in the Dell PC has one Dual Link DVI-I, one Dual Link DVI-D and one Mini HDMI video connection. No display port... :(

Thanks Pat, In your opinion is the 650 worth the extra money over the 630? Does that extra 20,000 in contrast ratio really stand out? These two models seem to be the two choices that i have narrowed it down to.

I would like to know about this also. I have read in some reviews it has a different screen than the 650, less glossy?

Yes you can. You can upgrade to a GTX 650 without having to upgrade the power supply brick. You can also upgrade to the GTX 660 but you will need the larger power supply brick which is about $140.00. I have the GTX 645 in my rig and I love it. I'm playing BF4 at 1080P and it looks beautiful.

Windows Index scores the Asus GT 640 2GB as a 7.4/8 score. This card is ultra reliable, runs games at medium to high settings smoothly and doesnt have a loud profile. Ive enjoyed the hell out of this card on my back up gaming desktop.

What Zachary said. 650 watts is more than enough power to run that card and a bunch of HDDs, disc drives, and peripherals. You picked a great card, too. Not too loud or hot, plays today's games with maxed out settings at a consign at 60 fps or higher and I've had no driver issues to date. Happy gaming.

For me, the important difference is that this card has 2GB of memory while the one I purchased has 4GB of memory. I'm a 3d-art hobbyist and use an unbiased-renderer that depends on the GPU. I can build a scene using the 4GB card with a complexity that requires twice the memory of the 2GB card. This makes a big difference for me. Gigabyte is a solid brand, they feature a well designed heat sink. I'm extremely happy with my purchase of the GTX760 4GB card.

Yes, there is one PCIe-x16 slot available, which is what is recommended for the GTX 960.

Michael: Thanks for the excellent comparison. Until I read your comments, I had about decided to go with the 700. I'm ordering the 750 instead. Bob F.

I believe the 650 is 12bit color processing and the 750 is 16bit color processing as well. Lately the 750 is CHEAPER than the 650 currently on here by about $25, but when I got my 750 at hhgregg last week it was $300 cheaper than the 650 O_o

Nvidia geforce gt 640 has twice the ram and a higher cuda count for just a little more. I bought the diamond card and was disappointed with it. Useless for modern gaming but decent for Blu ray.

I believe the 750ti is something on the order of twice as fast as the 650ti, not to mention more efficient. http://www.anandtech.com/show/7764/the-nvidia-geforce-gtx-750-ti-and-gtx-750-review-maxwell

The 550 is 30000:1, The 650 is 50000:1 There is a big difference in PQ of these two sets.The 650 being better.

The 6300's do not use all Samsung parts and do not have a high enough picture quality/refresh rate in order to support 3D. The 6400's use all Samsung parts and have a high enough picture quality/refresh rate in order to support great 3D picture. Also the 6400's have Micro-dimming that gives you much greater contrast in the picture and allows for deeper black areas.
