Project Cars
Minecraft

Added (2). Just Cause 3 instead of Minecraft.

Why does my new GPU perform worse in Minecraft than my old one?

I just got my R7 260X, and I upgraded from a GeForce 8600 GTS. The new card should perform a lot better, but it performs a lot worse in Minecraft than before. In other games it's perfectly fine, so I don't know if it's an optimization thing.

Why can't I download Minecraft Windows 10 edition?

I recently installed Windows 10, and I found out I could get Minecraft Windows 10 edition for free, so I got the code, now it's ready to install.
But whenever I try to install it, it says 'Well, this is embarrassing'. When I click on 'See details' it says that it can't find the app.
I've clicked on retry many times and it keeps saying the same thing.
Now it's downloading 84 mb when the game is only 74 mb.
Can someone please help?

Will my programs work in Windows 10?

The programs are:
Photoshop
Sony Vegas Pro
Camtasia
Microsoft Office / Powerpoint, Excel etc.
Minecraft
and more.

Will they all work?

Looking to purchase new Laptop?

I'm looking to buy a new laptop. I will mainly use it for gaming but I have a smallish budget of roughly $800. It needs to be able to smoothly play Skyrim, Counter Strike global offensive, Civ5, TF2, minecraft and other similar games at medium or preferably high settings. I'm not after a des top as it needs to be a little portable. Please can I have some advice?
