Can my current system support these display upgrades and should I go ahead with them?

Hi everyone, I've had my current PC for about 3 years nearly, and for the last few months I've noticed it struggling to play games at full, or even medium graphics and it's become very loud when playing them (GTA IV, Left 4 Dead 2 etc.). It was never a perfect gaming PC however I have noticed a performance hit and have avoided playing games for a long time in fear of overheating. I've cleaned out dust a couple times as recommended all over the internet but this gave really minimal performance boost. I guess my question is 1. Does it sound like I should upgrade my graphics card to take away some strain and thus lessen the overheating and also boost my gaming performance (most important for me), or should i look at getting a new cooling/fan system to help cool down the pc (I've assumed that despite making louder noise it isn't necessarily overheating the parts are just working harder thus a graphics card upgrade would help)? 2. If I were to get a new graphics card, I am really eager to purchase a 'HIS HD 7850 IceQ X 2048MB GDDR5 PCI-Express Graphics Card' which has great reviews (especially on its fan/cooling ability) and a great price, I think I'm sure I could run it but would my current specs (below) run it? 3. Would these same specs be able to support a 'Viewsonic VX2370SMH-LED 23" LED 1920X1080 IPS 6MS Monitor'? As my current monitor is about 5 years old!!

Thanks for any help that could be provided, nothing worse than when your gaming pc starts losing performance! As a novice on hardware I understand I may have not have a grasp of how everything works so any help/corrections etc. is/are appreciated!!

Thanks, Henners

Depending on the HD 57xx card you have, I would say it is your main problem. Not much graphics power there. The rest of the system looks good except for one thing... we need to know the make/model of your PSU. Or maybe you can open the case and see if the nameplate on the PSU is visible to read the specs. If it is a good quality 450W PSU or better, it should be fine for the HD 7850. That card shouldn't exceed 130W maxed out. That relates to less than 11A on the _12V rail.

Thanks for the speedy reply! Good to hear a new graphics card might be just the change my PC needs, only question is on the official HIS website (http://www.hisdigital.com/un/product2-690.shtml) it recommends at least a 500W power supply, are you saying I should ignore this?

No, I wouldn't say to ignore it. Just take it with the proverbial "grain of salt". The manufacturers don't have any idea what else is in your system, so they figure high for safety sake. The best bet would be to use a PSU calculator. That way you can enter in the exact devices/specs of your system and see where you stand.

I was just saying that if you have a good quality 450W PSU, you can probably get by without upgrading it unless you notice shutdowns or re-boots occurring. That is usually an indicator that the PSU can't maintain the voltage during stressful periods.
If on the other hand, your PSU is of low quality, by all means upgrade it to a bigger, better unit.
