Thinking of upgrading my prebuilt computer so that it will be better for gaming.
Currently, I have an HP Pavilion Elite HPE-410t, which comes equipped with an AMD Radeon HD 5570. That, coupled with a 300W Power Supply which is probably woefully inefficient, isn't quite cutting it. I was wondering if it would be possible to upgrade this computer with a beefier and newer graphics card (I had been thinking of an NVIDIA GeForce GTX 760, it seems pretty good for a fair price), and a PSU that can actually provide the power this computer needs, from a credible manufacturer. That being said, I had a had a few questions:

1.) Is that graphics card compatible with that motherboard, which, so far as I know, only has PCI-E 1.0 (The graphics card uses 3.0), and is it a good choice? I have read that, if it is compatible, the 1.0 on the motherboard will hold back the graphics card, if that is so, by how much?

2.) How much will the CPU on this computer bottleneck it (Intel i5 760, Quad Core @ 2.80GHz), if at all?

3.) What kind of Wattage/Amperage/Efficiency would I want on a PSU for that computer, upgraded?

4.) What kind of performance increase could I expect?

5.) With the above in mind, would it just be better to build a new PC from scratch? I could probably pull together a $1,000 budget, but would the finished product be better enough to warrant buying a new motherboard, processor, etc.?

For reference, here are the specs, listed out:
Motherboard: MSI-7613 (Iona GL8E)
CPU: Intel Core i5 760 (Quad Core @ 2.80GHz)
RAM: 8GB DDR3
Graphics Card: AMD Radeon HD 5570
 
Solution
1) Yes, the PCIe protocol is backward compatible, but you will lose some bandwidth at PCIe1.0.
2) Not too bad. The 1st gen Core processor is still a good gamer with cards of that class. The PCIe 1.0 bandwidth would be more of a concern to me.
3) Brand Name good quality 600W or better PSU. The GTX 760 is a 170W card. 14.2A on the +12V rail.
4) A LOT! http://gpuboss.com/gpus/Radeon-HD-5570-vs-GeForce-GTX-760
5) Yes.

Trying to upgrade this would bring more problems than answers.

You would have to replace the motherboard because fitting a Pcie 3 GPU on a motherboard with Pcie 1 will make it extremely inefficient and lag even if you had the newest CPU.

Power Supply - This would be a must if you upgraded because a 760 draws atleast 200W from the wall as well as all the drives and CPU and everything else in your computer would bump this up to 500W atleast. So you would need to upgrade that to about 650 or 750W Power supply.

The Cpu isn't the fastest, and would need to be replaced too.

So overall, it would probably be cheaper to buy a new computer, A - Because it would come with no bottlenecks/hardware complications

and B because you get the case and components YOU want.

Have a good day :)
