4830 or 9800 GT

Im having the same problem, im running an ATi X1950 XTX but wanna upgrade to either the 9800 GT which is around £99 in the sales or the ATi 4850 which is around £145, but ive had problems with my last 2 ATi cards and im not sure its worth spending the extra 50 quid to have more problems.

4850 is still the best price/performance!

^i disagree... 8800/9800GT ftw price/performance.

it depends really. if you're playing the majority nvidia games, get the 9800GT. if you're playing ati games (source engined games mostly) get a 4830.

^ In jan the new ATI drivers are ment to make the difference between nvidia games and ati games undetectable, so i wouldn't buy a nvidia card just cos u play crysis alot anymore

Myu question was will my mobo able to run those two cards.I mean whats al lthat PCI-E and PCI-E 2 thing.My board,i think is PCI-E and these two are PCI-E 2.So will my board handle either of these.

Cooling is a big consideration now. Take advantage of the different cooling solutions being offered. We no longer are stuck with the basic reference cooler. I just lucked into a 9800GTX+ from Asus. It has 4 heat pipes / sinks, and a rotary fan centered right over the chip. Runs cool as a cucumber, and it will be so easy to clean THOROUGHLY, as nothing is hidden under a cowling.

I don't understand why for all of these years, and continuing, some manufacturers still ship out cards that are destined to run smoking hot out of the box, let alone when you start getting a little dust buildup.

all pci-e 2.0 cards will work in ANY pci-e 1.1 slot, so as long as your mobo isn't from the 90s, you should be fine. the only problem is that pci-e 2.0 is twice as fast, so it could slow down high end cards, but with a 4830 or 9800gt, you should not notice any speed difference, only if you have a gtx280 ors 4870x2. the 4830 destroys the 9800gt, it overclocks like CRAZZY, if you can, get the msi version, its the best overclocker and even uses less energy then the stock ones (because it uses solid capacitors and ferrite chokes=cleaner power and better volteges). most 4830s reach the max limit of 700mhz, which is 20% higher then stock.

If you love AA pick up the 4830.

yes, ati 4xxx cards are very very good at aa and af filters.

question is: which will oc better?

the 4830 has a lower 55nm process, but it still runs VERY hot. the 9800GT on the other hand with a dual slot cooler would run very cool... leading to higher overclockability. however we all know heat is almost always NOT the limiting factor in a GPU overclock. thoughts anyone?

the 9800gt with hybrid power are @ 55nm, too.

and yes they're exceptional at AF/AA but a little weird and shaky with VSYNC ON (DMC4/NBA2k9/COD4, not on cod5 though) on my end.

anyway id get a 4830.
