There is no sense in upgrading the GTS 250 to a GTX 470 if you are on a tight budget. The GTS 250 supports hardware acceleration with the 'hack'.
The basic problem you have is the CPU/mobo. Upgrading memory to 16 GB looks like a waste of money and will not give you the performance boost you may be looking for. You can't use that memory on more recent mobo's, because of the DDR2 architecture, so the depreciation period is very short. If you can add memory modules to your current system, I would only add memory to 8 GB, not exchange sticks.
You better start saving for a new X58/i7-9xx/DDR3 system.
The big change in hardware land is not expected before Q3/4 2011 and as always, early birds pay the price.
Hi Harm as always you have answers which is very helpful ,but there are some things I forgot out sorry the GTS 250 is only a 512mb card, I want to replace the the gts250 as my son needs a gaming card and thought it would be a better just to give him the gts250 and I get a new GTX470 or maybe get a cheapter version and hack it so I am able to use the MP , the Motherboard is not a DDR2, but a DDR3 version of the motherboard and is able to run up 16gig ddr3 @1600.
Would I still not get a improvement?
This extra info is very valuable. With your son in the picture, a GTX 470 or maybe a 460 is very nice, both for you and your son.
The fact that you can use DDR3 makes it a new picture, because in that case you can continue using that memory in a X58 board. But rumors have it that the next big jump to X68 mobo's may use DDR4 memory and there is no one who currently knows the specifics. It is all rumors.
From a personal perspective, taking in mind that you may want to do this big upgrade early 2012, I still think that 2 x 4 GB would be enough for the time being, unless you can use DDR3 with the next generation of X68. Your major bottleneck is the Q8300 and memory does help, but not that much in your specific situation from going from 8 to 16 GB.
Thanks for the valuable info, it makes senes , so your suggestion is to go get another 2x 2gig ddr3 ram and have in total 8gig of ram is better and then wait for 2012 ...hope the world does not end as peridicted as for the GTX card the gtx460. In the end the cpu is the bottleneck oh welcome at least it will not be to expensive upgrade. Harm do you have any other words of advice that you may suggest?
Thanks for the help.
If you currently have 4 x 1 GB sticks, I suggest to replace 2 with 2 x 4 GB for a total of 10 GB
If you currently have 2 x 2 GB sticks, I suggest to add 2 x 4 GB for a total of 12 GB
Mixing memory is generally considered 'not done' and it may not work but there are numerous people who did it without negative effects. In the worst case you end up with 2 x 4 GB sticks that may be used in the next system.
Hi Harm thanks again I will follow your advise regards this.
