Choosing the Best Graphics Card Setup for Gaming
When deciding between using two good graphics cards in an SLI (Scalable Link Interface) or CrossFire configuration and a single superb graphics card for gaming, several factors come into play. This article outlines the key considerations to help you make an informed decision.
Performance
In most scenarios, a high-end, single graphics card typically offers better overall performance. This card avoids the issues associated with multi-GPU setups, such as micro-stuttering and compatibility problems with some games. However, when using two cards, certain games may not support multi-GPU configurations well, leading to diminishing performance returns. This variability depends on the specific game and the drivers involved.
Compatibility and Support
Selecting a single card is generally easier to install and is more compatible with a wider range of games. Developers often optimize their products for single GPU setups, making it easier for gamers to get the best results from their hardware.
On the other hand, dual-card configurations require a motherboard that supports SLI (NVIDIA) or CrossFire (AMD) setups. This means that not all games or applications will benefit from using two GPUs. In some cases, the performance of a dual-card setup may be worse than expected due to drivers or specific game optimizations.
Power Consumption and Heat
A single, high-end graphics card is generally more power-efficient and produces less heat compared to using two cards. Higher power consumption and increased heat output can be problematic, leading to the need for better cooling solutions and a more robust power supply.
Future-Proofing
Investing in the best single GPU available may offer better longevity as graphics technology continues to evolve. Single-card setups are more future-proof and adaptable, as the reliance on multi-GPU setups decreases with new game releases.
For example, a modern flagship card like the RTX 4090 can handle virtually any game, and additional dedicated GPUs may not provide significant performance benefits. Even high-end cards like the GeForce RTX 3090 can run demanding games without needing further upgrades.
Real-World Experience
Back in 2010, I built a top-of-the-line PC with an i7 930 CPU, a Radeon HD 5770 GPU, and the best components I could afford at the time. A couple of years later, I received a lower-tier HD 5750 card and decided to run it in CrossFire configuration.
3DMark performance tests showed very little difference, but some games, such as Crysis, saw almost a doubling of frame rates, even though the secondary card was only a 5750. This experience highlights the variability in performance gains when using dual GPUs, even with cards from the same manufacturer.
Since then, I have upgraded this PC several times as older parts have become cheaper, and it now features an i7 9900K running at 4.2 GHz, a Radeon RX 480 with 24GB of triple-channel DDR3 RAM clocked at 1800 MHz, and a 1TB SSD connected to the motherboard's SATA 3 controller. Despite these upgrades, I have considered retiring this setup many times, only to find that newer, cheaper components are constantly becoming available, delaying the inevitable.
Conclusion
In most cases, a single high-end graphics card is the better choice for gaming. It offers simplicity, better overall performance, and avoids the complications that can arise from dual GPU setups. Unless you specifically need large VRAMs or are enthusiastic about experimenting with multi-GPU configurations, a single superb graphics card is likely the most effective and future-proof choice.
