help please need to upgrade due to so noise

[icehunter63]

I recently acquired a Acer Aspire G7200 Predator, it's a few years old but barely used. I was wondering if there was any upgrades I needed to play games smoothly or if its fine by itself. Here are the details below:

Operating System: Genuine Windows Vista Home Premium 64-bit SP2

Processor: AMD Phenom 9750 X4 quad-core processor

System Memory: 4 Gb DDRII 1066 MHz

Graphics: ATI HD4850 512MB DDR3 supporting 2-way ATI CrossFireX technology

Audio: High Definition (7.1) channel audio support, Optimised Dolby Home Theater audio enhancement, featuring Dolby Digital, Dolby Pro Logic II, Dolby Headphone, Dolby Virtual Speaker and Dolby Digital Live technologies

Ports: 18-in-1 memory card reader (Memory Stick, Memory Stick PRO, CompactFlash Type I, CompactFlash Type II, SmartMedia, Secure Digital, MultiMediaCard, xD Card, 6 x Audio (7.1 channel support), Line Out, Mic-in, 10/100/1000 Network, 9 x USB 2.0, PS2 Keyboard, PS2 Mouse port, IEEE 1394

Hard Drive: 640 Gb Serial ATA

Optical Drive: SuperMulti DVD RW with Labelflash technology, DVD-ROM

Expansion Slots: 2 x PCI, 1 x 1X PCIE, 2 x 16X PCIE

Dimensions (WxDxH): 190 x 490 x 430 mm

One of the main problems is the noisy of the fan its like a jet engine along with slow graphic frames. I would like to change the fan but am a bit warry of what to change ie is it case fan or graphic card as soon as I oen the case I cant tell witch one is the culprit.

Ok I workex out the case fan is the culprit of noise it a 1200mm sqare fan so looking for a replacment any recommendations low budget also is it better to by a cheap new video card or get a second ATI HD4850 512MB DDR3 cost is a problem to top it off need to get more memory and I dont understand what to get so much out there want to put 4gig in there please pleasse help

My guess is that you will be limited by the graphics card in most games.

Try it out and see how you do with your games.

If you think you need more,

run these two tests:

a) Run your games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
This will simulate what a lack of cpu power will do.
Conversely what a 30% improvement in core speed might do.

You could also experiment with removing one core in the bios. You can also do this in the windows start configuration.
This will tell you how sensitive your games are to the benefits of many cores.

If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.

It is possible that both tests are positive, indicating that you have a well balanced system, and both cpu and gpu need to be upgraded to get better gaming FPS.
A graphics card upgrade is easy if you have a suitably strong psu.
With a typical prebuilt psu, the strongest graphics upgrade would be a GTX750ti.
A cpu upgrade has more issues involving a change in motherboard, ram, and os.
