Upgrading PC for Gaming

[Gwyn]

Hi

I have done some simple upgrades for my old computer (change graphic card, change processor) but it finely broke and I have just bought a new one which is not capable for most AAA games I wouldn't mind so much but Fallout 4 is coming out. I have just a few questions before buying the parts.

The parts i'm using now are
Graphic card - AMD Radeon HD 8570 - Secondary - AMD Radeon R7
Processor - AMD A10 - 7800
Motherboard - Lenavo Bantry CRB

1. Can I change the processor from a AMD Processors to a Intel Core i7 4820k Quad Core processor I'm just worried that they are different brands and I would have to stick with a AMD Processor.

2. For the first time I have a Duo Graphics card, can I replace one of them with any graphics card (I was looking at the AMD R9 390X G1 Gaming Card) or is there anything special I have to look out for.

3. I was also looking at buying the 850w Corsair CX850M power unit is there anything I should look out for when upgrading the power unit.

Thanks for any Help

Intel cpu's will only work in Intel sockets and AMD cpu's will only work in AMD sockets. Socket is the name given to a port or connector on a motherboard in which a cpu is installed. This does not mean that all AMD cpu's will work on all AMD sockets and the same goes for Intel. For both AMD and Intel, different cpu's are designed to work on different sockets, although sometimes multiple sockets may support the same cpu. There are so many different sockets and cpu's with different support that its hard to give a black and white answer.
This is important, if you are considering buying a new cpu then look on the manufacturers website and find out for sure what socket it is designed to work in. Once you have found a motherboard that uses the correct socket for the cpu you want, then you need to check the cpu support list on the manufacturers website to make sure the cpu is compatible with that particular board.
That's a good PSU to buy and 850watts would leave you with more than enough power for future upgrades if you decided to do any.
Right now you are likely using hybrid crossfire, the integrated gpu in your cpu and the dedicated graphics card. If you were to go ahead and buy the R9 390x then you wouldn't be able to use hybrid crossfire, which is a good thing as the integrated gpu would slow the R9 390x, so its fine to go ahead with that card.

1. Shlouski basically covered it.

2. Yes, you can add a different card and it'll be the dedicated gpu. Looks like you have the budget to build a new rig though. Nothing special but performance benchmarks and reviews on stability.

3. 850W is overkill but a 750w will be fine. Your goal is to get a PSU rated about 20% about your usage for optimal performance. You could use a 600W but would be cutting it.

Looks like you're gonna need a new setup. You have a prebuilt from the looks of it (the motherboard) and you'll be looking at a setup like this: http://pcpartpicker.com/p/YbB2dC
