Help me choose grahic card

[askara]

i just bought a pc from packardbell. quad core 2.3 GHZ. 4g ram and Geforce g100. runing window 7 RC and it is pretty bad at gameing. it has low framrate at devil may cry 4 at low. so i was going to buy a grahic card. having done a bit of reaseach i was confused like nividia rebranding, how higher number doesnt mean better and power suplyy etc. and i dont know which is the best, and compatible. so please help me choose a grahic card. my buget is around £100 or below. oh and does it matter if is it from pny or bfg etc?

here is full spec on the pc: http://support.packardbell.com/uk/item/?pn=PT.U090X.013&g=1400

monitor and speaker has seperate plug-dont know if that matters

ps will the game run faster if i downgrade to xp?

Your best bet would be to get a HD4670. Out of stock here, but you could look for a different e-tailer where it's in stock or cheaper.

One of the biggest limits on your graphic card is the power available from your power supply. To get a more powerful graphic card you'd probably have to upgrade your power supply also. XP wouldn't make an appreciable difference on speed.

so what is the max power i can get? is say 230V and 2amp at the back. does that mean i can use card with minium power supply requirment 460W or below?

and do i have a 6pin pci-e?

4870x2 ftw

 

[askara]

oh how come everybody suggest ati card in other post too? is it much better than nvidia?

How do you know wha tpower supply your computer is currently running?

 

[askara]

i dont no if i am right but power(watt)=voltage x amp and on my back it say 230v and 2 amp, so i guess my psu is 460watt. meh.. i am probably wrong.

shut down your computer, unplug it, remove your side panel, find your power supply. There will be a sticker on it that lets you know what it's rated at, look at the connectors, is there a 6 pin pcie plug? Blow the dust out while you're in there.

my recommendation:

9600 GT from NVidia
HD4670 from ATi

u can go to nvidia / amd/ati website directly to check its spec

anyway feel free to choose/buy card that u think best for u

 

[askara]

hmmm 250 watt?....but the Nvidia G100 require 300Watt. did i read the wrong thing?....geez guess i have to but a new psu. can anyone recommend me one? or does any one will fit?

HD4670 require 400watt also so if i can run that card then doesnt mean i can run all other too? like 9800gt

ohh i think i have a 6pin pci e

maybe a 4770 they use really little electricity for a great performance (40nm) and they are getting more frequent again (earlyer they were out of stock)

 

[askara]

my psu is FSP FSP250-60HEN 250W can anyone tell me if i can run 4770 or 4670 as they require 400w.

would it explore if i overload the psu?

 

[renz496]

maybe u should change your PSU.i think it is better to run the card with its recommended power as mentioned by the manufacturer. i don't think that your psu will explode but in return your pc might not boot up when u install those card into your pc.anyway check this:

not really sure if this useful.

 

[askara]

performance wise is there a bigh diffrent between 4670 and 4770? and what nvidia card they are equal to?

guess i have to upgrade a new psu.

 

[renz496]

i'm not really sure how big the difference between the two but many people recommending 4770. u can check reviews and benchmark if u are interested. as for your second question have u read tom's best graphic card for month yet? at the end of the article lies the answers for your question.
