Graphics Card Buying Advice Needed

Im planning for Graphics update of my PC. My PC having 300W Powersupply now. I can buy maximum 360W SMPS for this.

Which Graphics card need to select from these?

ATI Radeon HD 5450, HD 5670 and HD 6670

Also please guide me which powersupply can I select for this Graphics Card : 300W or 360W (not more than that as my UPS not support more!)

My system configuration is as list as below:

Intel DG41TY Motherboard
Intel Pentium Dual Core E5200 2.5GHz
2 x 2GB DDR2 RAM PC2 6400 800MHz
Seagate 500GB SATA2 HDD 7200RPM
Seagate 1TB SATA2 HDD 7200RPM
LG DVD+RW
300W SMPS
USB Mouse
PS/2 Keyboard
18.5" Wide DELL LCD Monitor

Why don't you upgrade your psu first? Surely you will not like to get your pc blow out. BTW, What is your budget?

Grab a 5670 and you will be fine.
My friend has a 250 watt smps and he has no difficulties with 5670 but if you are planning to go for 6670 ,then go with MSI 6670(5.5 -5.7k)+fsp saga 400(1.9k) w or corsair cx 430 w(2.2 k).

for ur system, look for 5670 or 6670 will be fine. U can look for 240gt as well. BTW, at which res u game ?

^^ 1366*768 most probably ;-)

@ OP - get either HD5670 512MB GDDr5 or HD6670 1GB GDDr5 whichever is in your budget.

For the PSU look for corsair VS450 @ 2.1k and tell us the brand and model name of the UPS you have.

Thank you all for reply

Because my UPS specification says 600VA. And I think if I purchased 400/450W it will be huge load on my UPS.
My budget is upto 7k, but high-end cards will overkill my system.

topgear is saying correct. My display resolution is 1366*768.

won't. 450W PSU won't extract 450W. maybe 300-350W only. also don't go over HD6770. your processor will bottleneck the GPU.

Are you suggesting that I should go with 450W SMPS. Are you sure it will work with 600VA UPS? Do I need to purchase HD5670?

A 600VA UPS has max load limit of 360W - now with a HD6670 /5670 your rig will need to draw 210-240W from the UPS and the LCD minitor will consume 25/35W - so the overall load on the UPS would be not more than 270W provided you are using a good PSu which has around 80% efficiency like CX430v2/VS450 - so the UPS will work just fine with a 450W PSu ;-)

Sorry if this question seems to be silly. How a 450W PSU can work with 600VA UPS if the UPS can draw a maximum of 360W? Is it there a chance of burning the UPS by connecting a 450W PSU?

I am using a corsair 550wt psu connected with 650 ups. So i think u shouldnt be worried too much.

Thank you so much! I will then buy a 450W PSU.
Can anybody please suggest a good PSU?

just get Corsair VS450 @ 2.1k or CX430v2 @ 2.4k ;-)

I wonder why is the price difference there eventhough CX430v2 have less wattage(430W) than VS450(450W)?

CX430v2 is a 80 Plus Certified Unit and VS450 has no 80 plus Certification ( 80 plus certification costs some bucks ! ) - this is the reason why VS450 is priced lower ;-)
