4850/4870: PSU ok? 512mb vs 1gb?

hi guys, i was building a new gaming rig:

-P2 x4 940
-gigabyte ma790x ud4 socket am2+
-sapphire hd 4850 512
-coolermaster eXtreme 600W
-2x2gb kingston 800mhz
-thermaltake soprano rs 101
- 500gb sata II 32mb
-19" monitor (already have this)

i think that the psu is ok for the 4850, but im also thinking on getting a 4870 isntead of the 4850

but, would the psu be enough for a 4870?

what about the 1gb versions? are they necesary for a 19 monitor? or is it a overkill?

what if in the future i got a bigger monitor? should i get the 1gb version?

does the 1gb version works fine with a 19" monitor?

hers the psu:

as u see, im not buying from the us
thx!

Does that PSU have four PCI-E power leads ? Each 4870 uses 2 of them, so if you ever plan to crossfire, you may want to check.

it has 2.. but im not planning in xfire for a long time..

when the time comes, i would consider if its worth xfire or a new gpu.. if xfiring, then i would look for another psu..

The 1GB won't make a difference in gaming...if you get x2 512MB cards in crossfire and x2 1GB you won't see much difference. The difference is seen in higher clocks, shaders and stream processing ^_^

i just put a gtx 285 on a 500w psu. ive read number varying from 500-700w. *shrug* seems to run games and not crash so im assuming its ok.

also, 1 gig does make a big difference. (especially at higher resolutions.)

Ok neon...

I was wrong...1GB does make a difference ^_^

ok

the psu has 2 x pci 6pin and 6 x 4pin
that will work for 2 4870 in xf?

i was also concerned about the 12V rail.
it says the following:

+12V1 18A

+12V2 18A

is that ok?

srry im insisting

well then go read some reviews. because i wouldnt touch a 512 meg card. i like high resolutions.

im not ranting, im responding to you. which is responding to me. takes 2 to dance. you might want to look in a mirror. also, name calling? really?

crysis warhead, 1920x1200 8xAA... the 1 gig card more than DOUBLES the fps of the 512 meg card. in many cases it just pads on 6-10 fps. which, is a lot in terms of high end videocard comparisons.

i should also point out, in those benchmarks, the 512 meg card is clocked higher.

i feel i had information to offer. and i did. wasnt ranting. it was helpful. you just dont agree. (and are wrong.)

if you are going to be running a 32 bit version of windows realize that it can only address 4 gigs of memory total. This includes the video card memory, so a l gig card will leave less than 3 gigs system ram even though you installed 4 gigs of DIMMs. A 64 bit OS won't have this limitation.

well, price difference for mine was only like 10 when i got it

ive been doing a lot of reading on videocards lately. i was on the market for a new one.

(which just so happened to have arrived today!)

i dont do a lot of shopping in spain. 25 euro difference? id get the 1gb. ESPECIALLY if you plan to crossfire. the realm changes entirely when you crossfire. suddenly, you have crazy gpu processing power... but no more ram. you will create a bottleneck with the ram (having to read from the harddrives every second is a real hit on performance.)

8800gt does not play crysis at 50+ frames on 1920x1080. period. sigh.

ok thx guys

ill get the 1gb if i decide on getting a bigger monitor

if i stay with my 19" monitor, ill go for the 512 ftw

it doesnt. not even close. barely anything does...

i agree, 30 fps is in the realm of reason. 50 @ 1080p, not even close.

im being lazy, but heres one example: http://www.nvnews.net/vbulletin/sh [...] p?t=103438

i could find 100 more just like it. and im sure you cant find me a single one with a 8800gt @ 1080p (or even 1680x1050) running at 50+ fps. not one.

i said i was being lazy. i dont believe everything i read. i believe the sum of everything i read. EVERYTHING says you arent getting 50+ fps. NOTHING says you are. nothing.

you should read MORE. you let me know when that 200 mhz increase on ram adds 20 fps to 30.

i also have to say, with every insult you fling you lose just that much more credibility. I havent insulted you on any level. Im just pointing out your mistakes.
