Try using HWMonitor Pro Trial and a third party GPU software to record GPU speed/temps
An R9 290X card has two GPUs on the same card. You can only have four GPUs in crossfire, which means you can only have two R9 290X cards installed in your computer.
You can use cross multiplication to solve this. 435/290 = x/100 435*100 = 290*x 43500 = 290x 43500/290 = 290x/290 150 = x 150% 435 is 150% of 290
Not likely as the power supply is only barely enough to power a Nvidia GT600 series card.
In 2015 the most powerful graphics cards are the GTX 980, GTX 980ti, and the Titan X from Nvidea. AMD has the Radeon 290, 290x, 390, and the 390x also.
Late 2013 and early 2014 has been and will be a very exciting time for graphics cards. AMD released the R9 270, 280, 290, and 290x recently. nVidia recently released and announced the 780Ti, a powerful upgrade to the existing GTX 780. You can read about any of these cards on a variety of websites including http://linustechtips.com/main/, http://www.anandtech.com, and a variety of other websites.
Cramer's Rule is used to solve systems of linear equations by converting those equations into one matrix equation. For example: ax + by = e cx + dy = f becomes |a bx|=|e| |c dy| |f| An example that I came up with just yesterday involved cell phone bills. It looked something like this: Cindy and Suzi just received their cell phone bills. They have the same provider and can see how many minutes they used and text messages, but they are curious to how much each text message and a single minute costs. Cindy's bill tells her that she used 638 text messages and 230 minutes for a total of $42. Suzi's bill showed that she used 290 text messages and 540 minutes for a total of $29. How much does a text message cost and how much does each minute cost? To solve this question, you would set up the information given above into two equations: 638x + 230y = 42 290x + 540y = 29 where x is the cost of one text message and y is the cost of one minute used. There are a lot of other examples in real life that you can set up like the following equations.

First, you are using an AMD processor that is five years old and therefore is not a very good option for modern games. On top of that, I have never really been sold on AMD processors. I've found that Intel CPUs are the better option and that is what I sell exclusively in my business.If you want to stick with AMD, then you will need to upgrade to a more modern CPU and, therefore, a more modern motherboard. Due to the excess heat that AMD processors generally produce, especially under load such as when gaming, you will want to consider at least a more robust CPU fan than what is delivered by stock. Suggestions for the CPU would be either Vishera or Zambezi-core FX-series processors. These will need a motherboard with an AM3+ socket.Next, your video card is woefully out of date: it was released in 2009, so that is about six years old. You need to get much more modern. Suggestions would be either a Radeon R7 or R9 series such as the R7 260X or R9 290X. Both are optimized for PCI Express 3.0 slots, so insure that your chosen motherboard upgrade has a PCI Express 3.0 x16 slot. After all, if you are going to do all this work, you may as well get all the performance you can, right?Beyond that, it looks like you may be "sharing" some of your memory with onboard graphics since only 2.9GB of the 3GB installed memory is showing as available. Thus, when you upgrade, go into your BIOS and make sure to disable onboard graphics (if any) to gain performance. Additionally, I would recommend installing at least 4GB on your new motherboard and would suggest doing so as two sticks of RAM for optimization by dual channel memory technology. There may not be that much performance difference between single and dual channel memory that you will notice, but even if it helps in the slightest, you may as well make it happen since the price differential is generally not significant between a single stick of the full amount of RAM desired and a RAM kit with two sticks totalling the desired amount of RAM.Finally, the hard drive is small by modern standards for anything other than a laptop. Given the fact that you are sharing RAM for your video and that your video is a "mobility" chipset, this tells me that what you have there is an older laptop. When you look at building a new machine, you will probably want to look at a 1TB drive. My professional preference is Seagate drives since they do not die nearly as often or anywhere near as spectacularly as Western Digitals. In fact, in my business, over the past ten years, I can count on one hand the number of Seagate drives I have seen fail while I can count far more WD drives that have failed since only the beginning of this year. You may pay slightly more for the Seagate drives but, as with all else, you get what you pay for.As a last suggestion, when you build this machine, make sure that you get an adequate power supply. For any machine intended for gaming, I never use anything less than 600 watts because of the demands of modern CPUs, video cards, and anything else that the user may wish to stuff into the machine after I deliver it. If you will be putting in a second video card at some point, invest a bit more money now and put in a 750-watt unit. Further, to save on your electric bill, look for a unit that is 80 Plus certified, preferably 80 Plus Gold certified as that will draw less power out of the wall to deliver what is needed by your machine. For more information about that, read an answer I provided at What_are_the_differences_between_bronze_through_platinum_power_efficiency_on_power_supply%27s.I hope all this helps.
