Hi guys,

I'm looking to upgrade my video card in order to improve gaming and general video performance. At the moment i have the ATI Radeon HD 5450. To be honest i dont really now where this stands on the graphics list but im guessing its not too great. Im looking to spend between £75-£125 maybe £150 if its worth it but dont know weather anything higher than the one i have know will be compatible with my pc. I read that i may have to change the motherboard and PSU. I hear that ATI and Nvidia are the two leading brands out there. If someone could give me a little advice and some possible suggestions it would be much appreciated.

Only low profile video card will fit in a slim case. U need to stay away from power hungry video cards because of 250w unit.
HD 5570 with DDR3
HD 6570 with DDR3

I didn't look up your system but kuwese is generally on the ball, so if you have a slim style case, you probably need a low profile card? Throw the Radeon HD 4650 & HD 4670 in the mix as well. They're a little older but still good cards. As kuwese alluded to, get a card with DDR3 memory rather than DDR2.

Will it make a difference if i got a higher PSU?. I take it there is no way of adjusting the case size either? Also why DDR3 over DDR2?...whats the difference? Sorry about all the questions just trying to understand how to choose the right one.

basically DDR3 memory is faster and better for gaming etc, than DDR2 memory.

these r all decent cards: ASUS Nvidia GT 430 1GB DDR3. (300W psu)

Sparkle NVIDIA GeForce 9800GT 1GB GDDR3 Low Profile version

ati radeon 5570 ddr3 1gb (i can vouch for this i have 1, its decent)

ati radeon 6570 ddr3 1gb

As for PSU, Yes usually the higher the number, the better it is!

Look up the specs of the card you are planning to purchase and then compare what you have to what is required to see if you need to replace it.
Most cards will recommend a minimum wattage, this is for the entire system but is only part of the picture.
Some cards will list the Amperage recommended on your 12V rail (a single 12V rail is preferred to multiple rails since you may end up with too little on one for your graphics card but extra on another rail that you will then not be able to access).
Look also for required connectors, some require a 6 or 8 pin graphics card connector that may not have been included on your power supply. Either avoid those cards or purchase a power supply that includes all you need.
Before you purchase a new power supply, make sure if you have the room for a full ATX, a MicroATX, or only a compact power supply, this will definitely need considering before you purchase.

You have to be a little bit crazy to keep you from going insane.
