would it be worth upgrading?

[paradisiac]

hi, got a 9800GTX+ for xmas and its a really nice card, but recently got a P5Q-E mobo which supports xfire (not sli ) so was wondering, would it be worth upgrading to a HD5770 with the intention of finally xfire, or using my 9800gtx+ for physx (if thats even possible), or is there not going much gains over just using the 9800gtx+?

yup i say go for it

yup i say go for it

which 1 though, go for the hd5770 and use mine for physx wait til i can get 2 hd5770s?
also is there much difference between the 5750 and 5770?

From what I've seen it's not a huge difference between the 5850 and 5870 but that is based on high res, max setting benchmarks on crysis and some other games so it's not like you'd expect and extra 20 frames on games like that. I think it's around 15% more powerful.

but what about the 5770/5750?

5770 is similar to 4870, 5750 - similar to 4850. The new cards have less power consumption, however, they're a little bit slower than the old ones.
2x5770=5870

Yeah do this, just have to grab the PhsyX Mod to use your 9800 with the 5770, and then grab another 5770 when you can, as they'll be faster than the 5870 in quite a lot.

Is it worth having a dedicated graphics card just for PhysX?

 

[paradisiac]

would it therefore be possible to have 2 5750/5770 xfire and the 9800gtx+ as a physx card?

 

[paradisiac]

anyone?

 

[philip j fry]

i imagine it would be possible (not sure how the physics fix works with this or if it does ) but would obviously need a mobo that could take 3 gfx cards

[paradisiac]

my P5Q-E has 3 PCIE sockets on it, which is what started me thinking

 

[Rroff]

Unless your playing batman AA or mirrors edge its prolly not worth keeping the extra card in for physics. There are a couple of triple A titles coming out that supposedly use PhysX as much as batman but thats not 100% confirmed they might swap physics API before release.

 

[philip j fry]

oh right then all you need to know is if the physics fix works in this situation anyone know?

 

[paradisiac]

is there a disadvantage to running 3 cards?

 

[paradisiac]

also can you xfire 3 cards?

is the hd4650 a really poor card?

 

[paradisiac]

no one?

 

[Dauthi]

Besides the heat/power not really.

but in Xfire they will run as 3x the lowest card. in SLI they have to be the same card type i.e all 260's

The 4650 isn't a bad card for the price but its for media/low res gaming.

What resolution will you be gaming at?

Edit: nvidia have stopped phyix working if an ati card is detected but there are workarounds. (not tried myself)

 

[paradisiac]

full HD res (1080p) if pos (most of the games i play run at this fine with my 9800GTX+).
so you can xfire 2 different ATI cards they dont need to be the same?
is it possible to run 3 cards in xfire, as in 3xHD4650?
if i was to get 2 HD5770 cards and xfire, that would cost £200-£250ish would that give better performance than buying a single card for £200-£250?

 

[Dauthi]

you can xfire them along as there in the same series i.e 3 ati 4xxx cards or 3 ati 5xxx cards.

2 5770 are best bang for buck for ~ £250 at. just above a 5870 in performane if i remember.
