Hi, I was wondering which gpu would be the best for my needs.
I have a 21inch screen, I use 1280/960 .. But could get a bigger screen in the future and would be happy not to have to buy a new gpu.
My config : asus p7p552, corei5, 750W Antec PSU, 4gb ddr3
my budget : 200$ CAD to 345$ (--- as a 2 year investment
Im mostly looking for high performance in game such as modernwarfare 2 and also game's that will come out in the future. ( I heard Dx11 was coming but is it in 1year, 2 year, sooner and will it be a drama if I use a card that support Dx10, I've also heard that that nowadays game were mainly using Dx10 ??
For $350 you can get 5850, a card you won't regret buying even after 2 years or so
However, if you can manage to add 450 MORE, you can buy 2 4890, which will perform better or on par with the NVIDIA's flagship GTX295($480)
DirectX11 is not very important, so if you want most thing out of your money go for 4890 CrossFire.
I would go with a 5850 for now over a 4890. Its a faster card and if in the future if you feel the need you can get a second 5850 in a year or so. The 5850 will be able to handle any game atm without problems.
You'll probably be OK with a 4890 for a year or two. I don't see DX11 becoming mandatory before then, and it'll still be a pretty powerful card in the meantime.
If you're nervous about compatibility, the 5850 is good for that price range. Either way you ought to be fine though.
For the money, I don't think nvidia has much to offer at this particular point in time. They're 6 months behind on DX11 and whatever they do come out with is probably going to be pretty expensive initially.
DX11 cards use less system memory with Aero in Win7... hmmm... Bad Company 2?..
I plan on getting a 5870 with my taxes but I'm waiting to purchase when Bad Company 2 comes out. no point in a faster card now with my 4850 and it runs everything fine. $400 right now, but I bet $300-350 by the time March comes around. And ma'b some Tax season discounts.
It's really your call,
If you wan't powerful gaming for long time, go with 2 4890
If you wanna save some money, go for 5850
5850 is still a great card but for $50 more you get a thing which performs on par or better compared to GTX 295
If you want to save money go for 5850 @ $350 range
If you want performance go for 5870 @ $400... I just saw 4 boxes at Fry's the other day($400 each).
2x 4890 is what i have and its better than 5870. Its logical to go for 2x4890 if you already have 1 and would go to beef up performance at ~$200.
Starting from none 5870 is a logical direction considering the following advantages:
1) You run with a single card with close performance as 2x 4890
2) Power saving is a lot better on 5870. A single 4890 consumes ~90W more at max load.
3) In the future you still have provision for growth for crossfire(add another ATI card).
Below is the benchmark for an OC 5870 vs crossfire 4890
But I've got another question pointing out..
Considering my corei5 processor, am I going to have a bottleneck.
this benchmark is excellent : http://www.tomshardware.com/reviews/radeon-hd-5850,2433...
They get real good performance with a 5850 or Crossfire Ati's card vs Nvidia's
But they use a corei7 975..
with my corei5 750, 2.66 Ghz (not too good at overclocking but I could give it a try. Still, it's not an i7..)
Do I have to take in consideration my pcu or not !???
Most likely, a single 5850 will be the bottleneck for an i5, but it will happen at such a high level that it won't matter at all - it's a "bottleneck" only in the most technical sense unless you're playing on a GIANT monitor.
An i5 and a single 5850 are a pretty good match, and any worries about a "bottleneck" are just splitting hairs IMO. It will be a pretty kickass gaming machine.
