Windows 7: Help with buying HD5870 - PSU Good enough?

Help with buying HD5870 - PSU Good enough?

Will a corsair tx 650 be enough for a HD5870 video card?

Hi,
Im thinking of buying a HD5870 graphics card. I have a Phenom II x4 965 quad processor which im going to OC to 3.6/7. My systems specs (current) are as below:
PSU Corsair TX650w 52 amp on 12v rail
Phenom II X4 965
Mobo MSI C45 770
6gb of Kingston Hyperx ram DDR3 1333mhz O'clocked to 1600mhz with 1.8v
Soundblaster Audigy sound card
Artctic Freeze pro rev 2 cpu fan
2 regular 7200rpm Sata HDD
Pioneer DVDR/RW
about 5 case fans
my current GPU is a PNY GTS250 1gb

The other thing is will the HD5870 show a huge improvement in performance on my games (Crysis,BC2,Metro 2033) over the 250? If my psu is not powerful enough (Isuspect it is when i checked the corsair calculator) will I be better off with the HD5850 and again will it significantly improve over the GTS250?

Please help as I have the money available as a one off and really want to buy the right card?

Any help advice would be hugely appreciated.
Cheers

you would see a very drastic improvement in your fps... and hm.... how many volts are on the 12 volt rail?

If it were me (it's not) I would make a decision about the specific gfx card I wanted/needed based on my needs. If, after running it, I decide I need more power, I would upgrade the PSU.

BTW, I think many believe massive PSUs are required to run the machine - which is, generally not true. Consider one's house power supply: there might be a 200 amp service panel for the house but if you add up all of the breaker capacities, you find there might be 300+ amps worth. Fact is, one does not place a maximum demand on every circuit simultaneously. So too with computers. I have a Zalman 750 PSU but run an XFire array.

PSU = Ok

Huge difference = Significant improvements will be noticed - although don't expect to be running metro maxed...

For BC2, use the 10.4a preview drivers + the April 7 profiles over the 10.4 official for the improved loading time fix

Attachment 73032
Thank you for your answers all. Im not going to be running at hugely high reolutions as the monitor im using is a samsung 23" 1080p full hd so i am going to try and run at the tvs max res if I can. Will I be able to use this set up to run Bad company 2 at full? Rather like the idea of seeing myself get slaughtered constantly on multiplayer!

Also I would like to try and run Crysis at its highest settings if I can at either 720p or 1080p. Will this GPU run it at that?

Thanks also Pizzaman for your answer. Im kinda new at PC building and at the moment my CPU is the x2 550 BE unlocked to a x4 B50. The Phenom II x4 965 is to be installed on Monday as part one of my upgrade followed by the HD5870 within the next four weeks. I did look at the 5850 but im definately leaning towards the 5870 as I want the most powerful I can afford/run.

I tried metro 2033 at max on the gts 250 it got a little jerky on the first part when i went outside. Thanks for the recommendation with the drivers. Ive been using Nvidia cards since I started. Im a bit annoyed at nvidias driver updates as Crysis and crysis wh run better for me on the old 185 drivers from last year but i lose frames and eventually bsod with the newer drivers. Ive been switching between the two as BC2 artifacts on the older drivers! I dont think switching between is good for the card somehow.

Again thanks all for your advice- ive been trying to decide what card to get for the past week but im definately heading for the 5870. Just gotta got the wife to give me final authorisation!
