Question about video card trade

[JosephBAdams]

I have an XFX GeForce 7800GTX OC, and I am interested in swapping it with someone for a 7900GT. Does that trade make any sense to you guys? Just looking for advice (I have the "for trade" announcement listed in the FS/FT forum.)

It does make sense considering that the 7900GT will at least mantain the same performance as the 7800GTX at stock settings and at the same time consume less power. Now if you take the overclocking headroom of the 7900GT into consideration even without volt modding, and insane overclocking if you are daring and go ahead with the volt mod; I'd say its a deal.

Ashish, would you say that out of the box my GeForce 7800GTX OC is equivalent, inferior, or superior to the 7900GT?

i'd say more or less equivalent to the 7900 gt.But very poor OC headroom.U won't notice much of difference.But the 7900 gt will draw less power.
U won't notice much of a diference until u OC the 7900 gt.
If u are selling ur gtx,get the e-vga 7900 gt signature series cards.Those are OCed out of the box to 600 for the clock.But it's supplies are limited,so get them while they last.
That even gives the 7900 gtx a run for its money.And it only costs $360.

It depends on the clocks of your 7800 GTX OC. The two card have the same architecture just on different processes (110 nm vs. 90 nm). So which ever has the higher stock clocks will perform better out of the box. But I'd say that the 7900GT will have more overclocking headroom than the 7800GTX OC.

as an example i had the following experience with both. Both were using Zalman VF700cu and on a side note the 7900gt idle and load were about 10-15C cooler than the 7800gtx

BFG 7800GTX OC:
Stock:460/1300
OC:520/1400

eVGA 7900GT:
Stock:460/1320
OC:650/1950

I think u can appreciate the difference 🙂

without the volt mod u get a 7800gtx 512 pretty much guaranteed (without the 512 of course, same clocks tho). with the mod u get a 7900gtx. this trade is a no-brainer.

morgash,

damn. Impressive.

What broader cooling in addition to Zalman (if any) were you running when OCing that 7900GT out the wazoo?

Pish opsh this is a much better buy from eVGA and it'd only 20MHz deffierence and it's like 50 bucks less. http://www.newegg.com/Product/Product.asp?Item=N82E16814130016

i was running my normal zalman vf700cu in addition to OCZ purecopper ramsinks. Case cooling is 2 90 cfm 120mm fans in the front and back as well as a side vent for the xp-90. the core clock of over about 580 requires a quick and easy conductive pen mod. the ram goes all the way up to about 1600-1700mhz without the pencil mod. anything over about 1650mhz on the RAM is all for show anyway according to my benches cuz these things are core HUNGRY. i run my mem at 1950 for bragging rights only lol. it can hit 2ghz but i feel safer at 1950. if ya need to know anything else let me know, be glad to help.
