Suggest a graphics card for full HD gaming

[Gavin78]

looking at your pc you could do with upgrading the whole lot

[truthspeaker]

I just opened my tower case.
I have win power 750 watt
Model:- EA4G-750
Is this power supply any good for gaming?

The whole computer does not need upgrading because windows 8.1 runs really good on it.

Most games will work on intel quad core 2.4GHz and 4Gb RAM

There are still shops selling pcs with quad core processors using 400watt PSUs.

When u take into account the CPU, Hard Drives, USB and so on and so on it doesnt leave much room for expansion.

400 watt is perfectly fine for a quad core CPU and a high end graphics card. A decent quad-core CPU (non overclocked) uses a maximum 60-80w of power. A high end graphics card uses 200w of power. Hard drives, USB and so on use less than 10w put together which means your total is still barely 300w peak, assuming everything were running at max at the same time.

I have a 430w power supply which is perfectly sufficient for two quad-core processors, one of the most power hungry graphics cards on the market, a ridiculously inefficient motherboard, and ten hard drives. This 430w supply is actually rated at a peak output of 500w, and I have seen it draw 530w from the wall before the safety cut-out kicks in.

I also have a 430w power supply in a server system with a quad-core Xeon processor, twenty-six hard drives, and three server RAID controllers, which at full load, uses barely over 200w. That still leaves enough space for three of your graphics cards.

I also manage a server system at work with dual 8-core Xeon CPUs (16 cores total), 128GB RAM and six 10,000 RPM SAS hard drives. That system uses 328w at full load. Still enough overhead for your graphics card - on top of two Xeon processors 128GB RAM and 6 server hard drives on a 400w power supply.

Seriously, some of the numbers some people come up with are absurdly over-inflated.

try the above it will give you an idea on your current system on what games it will play and also an indication on roughly what setup you'll need if not...

It doesn't have Far Cry 4 in the list

Far cry 4 is not out yet

It's even almost accurate, at least on the basics, until you start adding any drives. Then it becomes way off.

I have used that in the past, and almost got burned so now I don't touch it.

My pc will run in it's current state of a 750w psu, but that site say's I need 1.2kw unit by the time I have added in all the fans, pump and other bit's.

I use a 1Kw unit simply because it was spare from my previous build but my next build will probably only have a 850w in it.

The 8 core CPU if they went for that can use between 125 and 200watt.

Wrong again. I have 8 core CPUs that only use 95 watts, which is also the average wattage of all 8-core CPUs released this year. The maximum any current Intel 8-core CPU uses is 130 watts. There are 8 core CPUs that use as little as 12 watts (though they don't really count since they're Atoms) and standard Core i7-based Xeon 8 core CPUs that use as little as 60 watts. Again, those are maximums. Average wattage will be closer to 5 watts.
