Looking to buy a new tablet!

[Taylor Mack]

First post here.
Not sure if I am in the wrong thread.

I am looking to upgrade to a new tablet. Currently I am using an Asus Transformer Prime. I am stuck trying to decide between a few, and would like some input on what others think.

So what table should I upgrade to?
Asus Transformer Prime to....
1. Nexus 10 --- (not sure what accessories are good for it)
2. Asus Tranformer Infinty tF700 --- (love the keyboard option)
3. Samsung Galaxy Note 10.1 --- (the s-pen is great for drawing and note taking)

(My tablet usage)
Browse Web
Netflix
Notes for school
Hardcore gaming.

Any suggestions on what I should upgrade to? or is there a better tablet out there? looking to only spend 500$ on the tablet it self.

Thanks in Advance!
