And is was wondering if these upgrades would be ok to put in without causing any problems

And an AMD 7850 GPU

So would this work without any further modifications?
And if so which version of the 7850 should I purchase?
Finally would the GPU fit in the case?
Would there be any other gpu's better suited to my needs?
I am playing 1600x900, I do own games like BF3 but im not looking for the major super high def experience, just playable whilst looking ok will do for me..

If there is any more info required i will be happy to put it in

Cheers.

As long as there is room in your case and your power supply can handle it, you should have no problems. The 7850 should net your high/ultra settings on BF3 and maybe some AA.

If your case has poor airflow, I would opt for a blower style fan. If there is an empty fan slot, grabbing a fan for the extra airflow would also be well worth the 5-$20 depending on what type of fan you get. With good airflow, buying a non reference model like MSI's Twin Frozr or lightning series would give you better temps, and more OC headroom.

Edit: Is your monitor limited to 1600x900? I would put it on craigslist for a decent sum, and pick up a 1920x1080 monitor, otherwise you wont be getting the most out of your system.

Well my computer is about 3-4 years old so would it be better if i got a new power supply and what sort of W would i need to look for?
Edit: Yeah I probably will get a monitor sooner or later but right now i want to focus on the computer..

 

[aaronstyle]

if your psu can handle it you should be fine, how many watts is it, and how many amps on the 12 v rail? and what is W?

Ok so i have opened up my computer and took some photos, i believe my computer has a 250W PSU.
So my questions are.

Will the gpu fit? (assuming i buy this one http://www.aria.co.uk/Products/Components/Graphics+Cards+-+GPUs/Graphics+Cards+-+AMD/Radeon+HD+7850/MSI+Twin+FrozR+III+HD+7850+OC+2048MB+GDDR5+PCI-Express+Graphics+Card+?productId=49689)

Would i need any extra/different cooling?
My friend said that I should take out the heatsink system and the cooling fan and clean it out then put in some Arctic Silver Thermal Paste then put it all back in.

What sort of PSU would you guys recommend? (In terms of wattage/type)

With regards to the psu, would this be enough?
