Hey there guys .. I now have enough money to EITHER buy an ATI sapphire 5770 DDR5 1GB OR crossfire an ATI 4850 1GB Vapor-X card ..
my current specs is :
AMD Athlon 2 x2 245 2.9ghz am3
Asus M4a785TD-V Evo
Tagan stone rock 600W
ATI 4850 Vapor-x 1GB
Mushkin DDR3 2gb
Kingston DDR3 2gb
Windows 7 Ultimate
Samsung 320GB HDD
Please guys .. tell me is CF 2 4850 vapor x worth it ?? will i really see a performance change ?? or should i use the money and get a 5770 to replace my 4850 instead.. or shud i just use the money and get an AMD Phenom 2 quad 955Be..
Id also like to know if u recommend me to CF , is my PSU Wattage enough ?? thanks !
Crossfired HD4850s will certainly give you much better performance than an HD5770. The question is whether that PSU can handle it. If it's a quality unit then it can probably handle 2 HD4850s but I've never heard of that brand. I'm not an expert in such however. How many amps does it claim to have on the +12v rail? It should list that info on the side of the PSU.
hello maziar .. my desktop is running at 1920 x 1080(recommended) max for my Acer P225HQ monitor (21.5") for my games .. COD4 i run at 1920 and games like crysis/farcry2/prototype i run about 1280 coz of the lag ..
Hey Jay .. yea im afraid of my PSU as well .. erm what do u mean by "CF setups generate alot of heat" .. how will differ from a single 4850 generating heat ? meaning if its CF'ed they will both get hotter easier ?
A 2nd card will give you a far better increase than a CPU upgrade. You have (2) 22A rails with 528W/12v=44A. Your CPU does not use much power at all, so you would be pretty safe. Just don't OC them like crazy. Oced video cards can really draw alot of juice.
If those specs on the PSU are close to reality than it should be able to handle two HD4850s. For your resolution upgrading the graphics is definitely the way to go for now. A quad core is a good idea for the future but another card will definitely benefit you more for gaming at the moment.
and also id like to know how much performance boost will i get ?say currently im running my Far Cry 2 in all medium/high at 1280 reso and runs at 50 fps avg .. if i slot in another card .. how much can i boost it ? full 1920 ?
No that's not good,16x4x is the worst CrossFire configuration and won't perform as well as dual 8x or dual 16x,it won't allow your cards to show their full potential,so its better to go with a single card
I dunno, that article's results seem a little... odd at best. Looking at the performance summary at 1650x1080 the two charts show 2 HD4870s scaling(at most) 5% and 17%? Even at 2560x1600(low quality) they scale at only 28%. Those are terrible results. Basically that article seems to be saying the only time it makes sense to crossfire HD4870s is at 2560x1600 with eye candy. Is this an accurate interpretation or am I missing something?
