Solve : Add a Video Card to an FM2 AMD A6 Rig?

Answer»

Hi;

About 3 years ago I built a budget Gaming Rig using the following components:

ASRock FM2A75M-DGS Motherboard
AMD A6 5400K

2 x 4G Crucial Ballistix DDR3 PC3 Memory

I opted for this build as the AMD A CPU range include a GPU which for the A^ is I think a Radeon HD 7450D. Last year I bought Alien Isolation and never played it because the graphics were quite laggy.

Anyway time has moved on and I was wondering whether I could realistically upgrade this rig by adding a decent 'ish' video card for under £100.

I have been out of PC building since this build and Gfx cards have moved on somewhat as such I have no idea how the various GEFORCE GT / GTX cards and Radeon cards stack up?   

Any advice would be great.  Quote

Don't even get me started on that. They seem to purposely design their naming schemes to be as confusing as possible.

I expect that, with few exceptions, most of the dedicated graphics cards you can find today should out-perform the integrated Radeon graphics you've got in that SYSTEM. From what I can find, the 7450 was release in early 2012. I won't look at ALL the specs but two important ones are Pixel fillrate and Texture fillrate, which in it's case are listed in the specs I can find as maxing out at 3.0 and 6.0 respectively, and a 64-bit memory bus. This is technically for the desktop GPU variants (which were apparently OEM) and I'd expect it to be lower for the ones integrated as part of a Desktop APU, but they are a reasonable baseline.

I used Amazon and filtered graphics cards to show items below $100 USD. Here are some possible options I found:

A Radeon R7 240.

Pixel Fillrate: 5.84
Texture fillrate: 14.6
128-bit Memory Bus

It's listed at around $70. I would expect that to be a reasonable upgrade.

Another option, going NVidia side, is a GT 740.
It's right at the edge of your listed budget and I expect shipping would actually put it over (~$91) but performance wise, from what I can tell, it

has a pixel fillrate of 15.9, and a texture fillrate of 31.8, which practically doubles the performance characteristics of the Radeon R7.

Now, all this said- I should ADMIT that when I need help with choosing a new graphics card, I usually resort to starting a topic myself, as many other forum users have a more comprehensive knowledge regarding graphics cards than myself. My approach here was to use amazon.com as I noted, show graphics cards between $50 and $100, and look up some of the specs on the  wikipedia pages listing AMD and NVidia graphics processors/cards and compare them from that.
You might be able to get more for your money with a 750GTX if you go with a refurb card. But there are some risks with going with a card that is a refurb such as when it was serviced to be fixed were all stressed or defective components replaced or was it a card that was overclocked and cooked and then sent back for repair in which only the 1 chip that lost under strain was replaced with others stressed but still functional. Sometimes the refurbs are actually parts that never had a problem at all but were just returned and tested and sold as refurb as well.

While I dont care for MSI brand components, this one seems like an ok deal for what you get. Just not sure if newegg ships to your country or not. http://www.newegg.com/Product/Product.aspx?Item=N82E16814127921

I tend to like getting certain parts brand new vs refurb. ALTHOUGH if the price is right I have taken gambles and came out ok with refurbs such as refurb 300GB SATA II Hard Drives for $12 each for a server that I wanted to put a RAID in. With 2 drives even though refurb the odds of both dying at same time is slim and so for $24 I had the drives needed for the mirror setup.Thanks for the advice everyone, I did some of my own research and found some interesting stuff:

I managed to find a comparison on videocardbenchmark.net which showed how slow my GPU would be against some common cards:

This helped me identify the modern gradin METHODS, a quick Google search also helped:

Anyway I found a Asus Nvidia GeForce GTX 750 Ti Graphics Card (2GB, GDDR5, PCI-Express 3.0) on Amazon for £94.98 just need to get the cash :-)
