im going to be playing starcraft 2 on low settings unless my computer could do better and thats about it beside goin gon the internet but i would never go on the internet and starcraft at the same time
Also are you sure that these will work i just want to double check (im not doubting you)
The manufacturers product page for the video card says you should have a 400w psu in your computer. So it's going to be a decision for you to make if you want to try and run that card on a 300w psu.
The reason that a 400w psu is recomended is because along with the higher wattage comes more amps and the amps is what runs the card, so while it might not saturate the 75w pcie slot it does require a certian amount of amps to run. The two +12v rails on the 300w psu have a combined amps of 18a while the combined amps of the two rails of a 400w psu is 32a. So as I said it's up to the OP to decide what he wants to do and besides getting it to run the card is not very good for gaming so if thats the reason for the purchase then pehaps another more advanced card should be considered.
Yeah get ATLEAST a higher card such as the 5570 or equivilant... it honestly will BARELY run SOME games on low. You'll be getting 20 fps in most LOW QUALITY situations. the 5570 will be somewhat of an improvement and you should be able to run it on that psu. I >>>HIGHLY RECOMMEND <<< getting a better psu and video card if you want to game at all.
Also this would be a huge step up from my previuos graphics the nvidia 6150se right?
You'd get HUGE improvements with the 440 Gt. That case will give great airflow and you can use it in the future. SC2 is CPU intensive, that's why those guys can run it with that card. You can help shorten your loss with a better gfx card, but you prolly want to upgrade your processor after you upgrade your gpu. You'll most likely get towards the higher end of settings if you get the card... for not that bad of a price.
So i should upgrade my cpu also too what? and is theyre anythin gunder 50$ if not thts fine
You don't need to now... Your CPU will suffice. Because you'd need to get a new motherboard. And if you want to get a motherboard, gpu, cpu, case, and power... well hell.. just get RAM, use your old Hardrive, and build a new system.
