Considering CF upgrade

[Calgar117]

Hi Guys

I have a Sapphire 5870 currently running on my rig and i am looking at purchasing another to run in CF would this be a worthy investment?

also with regards to my PSU i am currentyl using would it be sufficient for this?

Rest of my specs are pretty simple

I7 920 at stock
Gigabyte UD5 mainboard
6 gig ram
1TB HDD

I also have a Coolmaster storm case and it bearly fitted the 5870 due to some odd reason them putting the psu connectors on the side of the card instead of the top so in order for me to get another card in there would require to remove part of the internal casing for the HDD bays.. lol

what do you guys think?

With everything left at stock, i should think that HX750 should cope. And 5870 crossfire is a cracking setup, and i belive your UD5 will leave a sufficient gap between the two cards for cooling.

With any kind of overclocking though you should be looking at an 850+ psu, you might want to invest in 1000w psu in the future to continue crossfire/sli availability for many years to come(corsair do 7yr warrenties on their latest psus)

Hope that helps, dont take it as gospel though

Ur 750W PSU will be fine even with OCing. Power draw on a system with xf 5870s is approx 600W so another 150W is plenty of headroom!

Most important question - what resolution do you use?

I run on 1920x1080 performance wise is good at the moment but getting £400 so thought what the heck might be worth while investment of setting up CF on my rig

on one note the 5870 is such a cracking card chuffed to peices with it.

It certainly is, i cant imagine u need to buy a second...SSD instead, new haircut, pizza?

Personally would rather get a nice big SSD, I have found my single 5870 excellent at 1080p. The only reason I would want another is for Metro 2033, but really just knocking the AA down a bit keeps it above my target of 50 fps.
